If writing by hand, write clearly, legibly, and neatly so that anyone, especially your TA, can read it easily. the two balloons together, but they kept moving away from each other. This can happen when two non-conducting materials are rubbed together for example plastic and fur. Do not bring the heat lamp too close, or the insulators will be melted. Both the negative and positive charges have the same pull/push strength that can affect the positively charged puck and they are different in the way they affect the puck by either pulling or pushing. Record in your notes the relative humidity in the room (from the wall meter) and the inside and outside temperature. Remove the sliding ball and record the equilibrium position of its inside edge that faces the sliding ball, which you will subtract from all the other measurements to determine the displacement \(d\). The hanging ball should be centered on a line with the sliding balls. This part uses the Charges and Fields simulation from PhET Interactive Simulations, Learning Goals: Students will be able to describe and draw models for common static Surrounding a charge there is an invisible electric field which gets weaker the farther away one gets from the charge. Using Coulombs law, we can explore the effect of the distance, between two charged particles, on the force between them. It depicts how the gravitational attraction force for small objects is insignificant when compared to electrostatic charge. discussion. Most materials are electrically neutral they have an equal They were attracted to PDF Lab Report: Separating Salt and Pepper - Weebly Login projectile motion refers to design and light. If the negative rod is brought near an isolated, neutral conductor, the conductor will also be polarized. What happens? Science. So the balloons did move away from Electric field lines are typically drawn to visualize the field. Stuck on a homework question? Theory Charges and FieldsThis part uses the simulation from PhET Interactive Simulations, Learning Goals: Students will be able to describe and draw models for common static electricity concepts. The balls will share their charge, and half the charge will remain on the first ball (assuming the balls are the same size). Finally, consider the different concepts in which James Clerk Maxwell did research, and give an example of one of these concepts in use in your life. Record the results in your notes. Include and Analyze Final Data. In general, molecular compounds do not dissolve readily in solution and are poor conductors of heat and electricity.

Recharge the balls as in steps 1 4, and record a series of measurements of the inside edges of the balls. paper. The direction of this force is determined by the sign of the charges: like charges repel and unlike charges attract and acts along the line between the two point charges. Rub Johns foot on the floor to demonstrate charge transfer. Electrostatic charges | IOPSpark much stronger repulsion than when the non-sticky sides face each other. Static electricity or Electrostatics David Case: March 6, 2015 Experiment #8 Static Electricity or Electrostatics Objective: To explore the concepts of static electricity and to discover how many types of electrical charges exist and how they interact with each other Materials: However, if a neutral object is placed inside a strong electric field, the material may become polarized. transfer, induction and electric attraction. The polarization of charge in the insulator is small, but now its positive charge is a bit closer to the negative rod, and its negative charge is a bit farther away. Place the metal plate on the center of the lucite plate, and touch it with your finger. Usually, it is possible to calculate the currents and voltages in a circuit by solving a set of equations, the calculations are required to design a safe circuit.and this is one reason why advanced mathematics is so important in the field of electrical engineering. Move the rod along and around the top so you touch as much of its surface to the metal of the electroscope as possible. First, we observing what happens. Sweater will become electron deficient thus, making it have more positive charges. PDF Lab 1: Electrostatics - University of Michigan Does anything need to be held constant? When objects are rubbed against each other they acquire electric charge. For example, if you charge a balloon by rubbing it on your hair, it can stick to a neutral wall. For an additional credit of 2 mills, use Excel to fit a power-law curve to the data. In order for the balloon to stick to the wall you need to have rubbed the balloon on the sweater so that it is able to collect electrons, then once you place the balloon near the wall it will stay on it. Remove the lucite rod. The positive charges on the wall will move towards the balloon, while the negative charges will, What do you predict for the answer? The puck will move horizontally right if both the magnitude and the distance were the We are all familiar with the fact that rubbing two materials together for example, a rubber comb on cat fur produces a static charge. will attract each other. Materials such as metals are conductors. Apply to become a tutor on Studypool!

Procedure The general conclusion is that there are two kinds of charge, which are in some way opposite. In this lab report, three methods of separating salt and pepper from each other are tested. Electrons are essentially being transferred from the balloon to the sweater. After writing this essay, I have realized the importance of electrostatics in our lives. Figure 2 shows a Van de Graaff generator on the left and also shows some of the equipment that will be used with it during the lab. Gold was used because it is a good conductor and very ductile; it can be made very thin and light. 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.
