Part 1: What is an equipotential line and how is this simulation related to work and energy?
1) Turn on “Show Numbers”
2) Place a positive 1 nanocoulomb charge near the center of the screen.
3) In the lower left of the screen is a meter for indicating electric potential, in volts, created by the charge that you introduced. Record the voltage and turn on “Plot”.
3.8 V

W = (V2 – V1) * Q
10) If the second positive charge were moved away from the first Positive charge, would this involve positive or negative work.
Since there is a loss of potential energy, no external force is required. Since the charge moves in the direction of the field, the field does the work
11) When energy was studied earlier in the year, a connection was found between kinetic energy, potential energy, positive work, and negative work. What is the connection?
The relationship between work and potential energy is that the work done by a force on an object to move it from point A to point B is opposite to the change in potential energy:
W =  (VB – VA) Q
This means that if the work done by the force is positive, the potential energy of the object is decreased. Let’s take the example of an apple that drops from the branch of a tree. In this case, Gravity does work to move the apple from the branch to the ground. Meanwhile, potential energy gets converted into kinetic energy when in motion and finally at the ground, the apple contains less potential energy. Basically, work is the change in potential energy.
A system consisting of a positive charge and an electric field loses electric potential energy when the charge moves in the direction of the field. Negative work means that the charge’s potential energy was converted into

Imagine if you made a batch of cookies and used way too many eggs, or not enough sugar. YUCK! In chemistry, reactions proceed with very specific recipes. The study of these recipes is stoichiometry. When the reactants are present in the correct amounts, the reaction will produce products. What happens if there are more or less of…

2194 Words  9 Pagesrisk. Due to the length of the Boeing project, at first glance it would appear a beta calculated using a longer regression period would estimate future returns best. The 60 month beta regression period began June 16, 1998. The 21 month beta period began September 17, 2001. Both ended June 16, 2003. This data is highly skewed due to the events of September 11, 2001 and the subsequent deterioration of the airline industry. In this case, the extended length of the regression period is a detriment to the…

The flow of current (+) is opposite to the flow of the electrons. ; note if toward or away from + terminal of the battery. The electrons move because they are being attracted towards the positive side of the battery and thus move because of the attraction in the battery. 2. What does the Ammeter (on the left) measure?
