), The displacement \(d\) of the hanging ball from its equilibrium position depends on the electrical force \(F\) which repels it from the sliding ball. each other. I have already completed the abstract, procedure, data and collections, but I have a hard time putting everything together and for the discussion, I only talked about what electrostatic force is and how electrons protons neutrons make up all matter and how when two different objects are rubbed together, electrons are transferred from one . Record your results. illustrates the direction of the field in a positive and negative char. How to write a lab report Every lab report must consist of: 1. 4.Ask Reflect on your answer to #2, write down how your thinking has changed. Have a class discussion. Fold one end to use as a handle. with sharing and discussing. What do you predict for the answer? when you rub a balloon on wool, this causes the electrons to move from the wool to the balloon's. illustrates the direction of the field in a positive and negative charge. Our tutors are highly qualified and vetted. An electroscope is a simple instrument to detect the presence of electric charge. Once you rub the balloon to the sweater, it gathers electrons so that once you place the balloon on the wall it will stay up and attached to it. Hold one end of the neon tube with your fingers, and bring the metal plate slowly closer to the other end. Explain your results. Slide 1 of 4. attachment_1. A metal ball (C)charged with static electricity can be lowered into the pail on a nonconducting silk thread. With the positive charge you can push the positive puck, and on the other hand, you can use the negative charge to pull the positive puck. Set the metal plate aside. gaining electrons now has more electrons and becomes negative. From the equation of Electric Field Charge (E=kq/r^2), we substitute our values of E (electric field charge), q (voltage charge), and r (distance) and solve for k. Solving for k, would give us the slope of the line m = k/r^2. Objects of the same electric charge repel, and objects of opposite charges attract. Your body thus acts as an electrical ground. Using Coulombs law, we can explore the effect of the distance, between two charged particles, on the force between them. In this section, you charged the lucite plate by rubbing it at the beginning, and were then able to charge the metal plate repeatedly. This is an electric field and electric potential lab. The puck will move horizontally right if both the magnitude and the distance were the same between the two charges. from the sweater then putting it up against the wall once it was filled with the negative charges. field with the positive puck. STATION repel, and objects of opposite charges attract. different charges in the same exact place, nothing would happen because they cancel out. After that, I then Electrons moved from sweater to balloon like predicted. The positive charges on the wall will move towards the balloon, while the negative charges will, What do you predict for the answer? The hanging ball should be centered on a line with the sliding balls. repel, and objects of opposite charges attract. If high-humidity conditions prevent you from completing certain parts, you may try them again next week with the Van de Graaff experiments. 3) Stick the "T" and the "B" tape to a surface, so that about 9 cm of the tapes are hanging freely in the air. You do not need to measure the position of its center, but will record the position of its inside edge. Record the results in your notes. Explain how thes InstructionsIn a two-page paper, identify the physics principles contained within the following scenario. Recharge the metal plate, and bring it slowly near the top of the electroscope. They are different in the way that a gravitational field acts on a mass and electric field acts on charges. If the cover sheet already has a title then use it as is. Assist the Continuous Improvement Manager on data collection, analysis, and compilation as it relates to LEAN projects throughout . Gold was used because it is a good conductor and very ductile; it can be made very thin and light. This can happen For example, to measure to position of the front of the hanging ball, line up the front edge of the ball with its image. After writing this essay, I have realized the importance of electrostatics in our lives. 4) For each of the following objects, determine whether they are repe. The title should indicate what the lab report is about. Electrons are essentially being transferred from the balloon to the sweater. Say Discuss with your partner what is happening when he touches the knob. Repeat the demo several times. Therefore the balloon material ends up with an excess of electrons and becomes negatively charged, while the other (sweater) ends up with a deficiency of electrons and becomes positively charged. HALIFAX, Nova Scotia, March 02, 2023 (GLOBE NEWSWIRE) -- ELCORA ADVANCED MATERIALS CORP. (TSX.V:ERA | Frankfurt:ELM | OTCQB - ECORF), (the "Company" or "Elcora . What do you predict for the answer? If so, how do you account for the difference? Opposite charges attract each other. If the humidity is high, as it is sometimes in the summer, the experiments are more difficult, and some may be impossible. Static Electricity Evaporation Dissolving The three methods will be compared at the end of this lab report. on the wall it will stay up and attached to it. When the balloon has been rubbed enough times to gain a sufficient negative charge, it, Wool is a conductive material, which means it readily gives away its electrons. A mirrored scale permits you to determine the position of the balls. separated (positive on one side, negative on the other). The difference between these two measurements, plus the diameter of one of the balls, is the distance \(r\) between their centers. Conclusion/Discussion At this point electrons will flow between the electroscope and the ground, giving the electroscope an overall charge. Rub the rough plastic rod with cat's fur, and bring this rod near the lucite rod in the stirrup. Write how the results of your Separate Salt and Pepper with Static Electricity Introduction: Static electricity is the build-up of electrical charges on the surface of an object or material. Electrons are being transferred from the balloon to the sweater. The reason why you can make a goal without hitting the puck is because we are using electric fields to move the puck. (Refer to the theory section, if necessary.). The plate acquires an excess of positive charge (since electrons have left this once neutral region) and the support/needle acquires an excess of negative charge (since electrons have entered this once neutral region). Step 2: Note down the reading on the ammeter and the voltage of the battery. Physics Lab Report. The arrows on the puck are illustrating how both the positive and Compute columns of displacements \(d\) (position of the hanging ball minus the equilibrium position) and the separations \(r\) (difference between the two recorded measurements plus the diameter of one ball). Hard rubber rods, which are also commonly used, become negatively charged. Using the values from the experiment, we found that the slope of the line is 1.51. PHY 2. same rule applies that similar charges will repel each other and opposite charges remained. The fundamental concept in electrostatics is electrical charge. In this section, you will observe the induced polarization of a neutral insulator and the transfer of charge by contact. If two objects are charged in the same way, they show repulsion. She found a charging station with a USB adaptor port. Coulomb's Law describes three properties of the electrical force: The force is inversely proportional to the square of the distance between the charges, and is directed along the straight line that connects their centers. hockey puck but they are on a high friction surface, so they stay in place allowing for Electrostatics Lab Name: Bryan Michel Materials: Styrofoam cups Styrofoam plates PVC Pipe Fur Scotch Tape Procedures: You will be investigating charging object by friction. In most of the exercises, you do not take data, but record a short description of your observations. equal to 9 x 10 9 N 2 /C 2. Once landed and inside the terminal, she turned her cell phone back on, but it was not charged. They were attracted to 1. electroscope. and rubbing his foot on the carpet, once he touches the door knob that is metal he is shocked or remain despite the sides the two tape pieces face. Lab 1.Electrostatics Goals To understand and verify the behavior of the two kinds of charge, denoted "positive" and "negative", respectively. (The heat lamp may help to minimize humidity near the pith balls.). 4 Pages. The electrophorus is a simple electrostatic induction device invented by Alessandro Volta around 1770. Basic Questions for Ohm's Law Lab Report Question: What is Variable DC supply? Because lucite is an insulator, it remains charged until the charge leaks off slowly. I tried to put User generated content is uploaded by users for the purposes of learning and should be used following Studypool's. Electric field lines are typically drawn to visualize the field. Once a charge is placed on an insulator, it will remain at the same spot until it is neutralized . spreadsheet. the positive charges of the sweater instead of each other. Cut 4 pieces of tape each about 10-cm-longh. A common instrument for this purpose is the electroscope, a device with two thin gold leaves vertically suspended from a common point. The answers from #2 and #3 support the results from the investigation since the It is created when materials are pulled apart or rubbed together, causing positive (+) charges to collect on one material and negative (-) charges on the surface of the other. In this simulation, a little different model is used. A static discussion. This can happen when two non-conducting materials are rubbed together for example plastic and fur. The puck will move horizontally right if both the magnitude and the distance were the For this experiment, I got the negative charges from the sweater for both balloons. Abstract: This lab focuses on Newton's second law and Coulomb's law. Electric Circuits 1 lab report 1. Conclusions Summarize what you learned in the lab, with specific references to the scientific concept under study which you detailed in the introduction. will have a stronger attractive force on its closest charges of opposite sign and a weaker repulsive Aug 2021 - Dec 20215 months. In an electric field, the system can be repulsive or attractive, whereas in a gravitational field, the systems are just attractive in accordance to its specific mass in its region. Does anything need to be held constant? However, if a neutral object is placed inside a strong electric field, the material may become polarized. The conductor has been charged without actually being touched with the charged rod, and its charge is opposite that of the rod. Charge the metal plate of the electrophorus in the usual way by rubbing the plastic base with silk, placing the metal plate on the base, and touching it with your finger. Metallic conductors allow the free flow of ions and electrons through a sample; and its conductivity decreases as the temperature increases.. This is explained by the like charges repel principle. The study of the Coulomb forces among arrangements of stationary charged particles is called electrostatics. PHY 2 Lynn University Electrostatics Lab Report . Typically, lab reports present data, discuss results, and provide conclusions. If you use two of the same charges to move the puck, it would move twice as fast, if you use two The purpose of this lab was to understand the idea of electrostatics AKA static electricity, and how electric charges interact with one another. device used for producing high voltages and creating static electricity. 4 attachments. Hold the metal plate by its insulating handle as far from the metal as possible. Try to estimate measurements to 0.2 mm. Lynn University. User Generated. Recharge the metal plate, and actually touch it to the top of the electroscope. Thus, the positive charge is attracted to the rod more strongly than the negative charge is repelled, and there is an overall net attraction. balloon. Both the negative and positive charges have the same pull/push strength that can affect A neutral balloon will gain electrons from the sweater. A. Rub the lucite rod vigorously with the silk cloth. We say that the rod has induced polarization in the insulator, but its net charge is still zero. If they are charged differently, they show attraction. InstructionsIn a two-page paper, identify the physics principles contained within the following scenario. slightly electrocuted. Static Electricity Experiment Introduction The purpose of this experiment is to separate salt and pepper by using static electricity. Lab 1: Electrostatics Introduction: This experiment is intended to give you some experience with, and experimental verification of, some of the basic principles of electrostatics you have been introduced to in lecture. What is the average distance a spark will jump? Conclusion from Ohm's Law lab Report We learned that current and voltage hold a direct relationship for resistive components. Since the rod is an insulator, charge will not flow from all parts of the rod onto the electroscope; you need to touch all parts (except where you are holding it) to the electroscope. https://phet.colorado.edu/sims/html/balloons-and-static-electricity/latest/balloons-and-static-electricity_en.html Charge laboratory: The lab will have two parts describing what is happening at both macro and atomic scales. The keynote speech delivered by Carl Sagan played a big r Our tutors provide high quality explanations & answers. Lift off the top cover and look down on the ball. Charge the electrophorus lucite plate by rubbing it with silk. (phet.colorado/en/simulation/john-travoltage). Diagram in your notes what happened with the charges. However, if a neutral object . They are classified as Nan-electrolyte compounds. 438v+3. What happens? Then we will utilize two classic electrostatic devices the electrophorus and the The This laboratory activity provides the opportunity to investigate the concepts of static electricity, electrical force, charge, and polarization. The balloons will move away from each other. have entered this once neutral region). The hanging ball will be attracted by polarization, as in Section III of this lab. Oct 2011 - Present11 years 5 months. Summarize the findings. d. How would the arrows look if the puck was negative? Place the rod into the stirrup holder as shown in Figure 7. Physics 2 Static Electricity Lab Report University The University of Texas Rio Grande Valley Course General Physics II (PHYS1402) Uploaded by Amanda Joy Academic year2020/2021 Helpful? SET thevaluesofq 1 to-7 Candq 2 to10 C. 3. I tried to put the two balloons together, but they kept moving away from each other. Move the rod along and around the top so you touch as much of its surface to the metal of the electroscope as possible. Create a portfolio of projectile motion sensor and experiments. With the charged object still held above the plate, the electroscope is touched. This experiment consists of many short demonstrations in electrostatics. Once again, recharge the metal plate. If the needle falls to 0 in 15 seconds or so, as it does on some summer days, you will probably have difficulty completing the experiments, even with the help of the heat lamp. You can stack charges on top of one another Use a Google Spreadsheet to document your data, graph and determine the equation for the relationship. What can we do to change some of the problems?Cite Plea 4.10 Graded Assignment: Resolving the Crime, Monroe Community College Statistics Worksheet. As shown in the demo below, the sweater is positive and the balloon attaches to the sweater due to the rubbing and the balloon essentially attracts to the electrons. How does the arrow from the positive charge compare and If not then add a title. Because the wall is also an electrical insulator, the charge is not immediately discharged. Electrons will actually move along this path to the ground. a If the angle \(\phi\) is small, then \(\tan\phi = \sin\phi\), and \(d\) is proportional to \(F\). to make the amount of charge vary. Describe the materials and fabrics that you found: For reference purposes, according to the convention originally chosen by Benjamin Franklin, the lucite rods rubbed with silk become positively charged, and the rough plastic rods rubbed with cat's fur become negatively charged. In general, molecular compounds do not dissolve readily in solution and are poor conductors of heat and electricity.
