Answer the questions below after watching the video
How is energy transformation different from energy transfer?
What point has the least amount of potential energy? Support your answer.
D because the cart has the most potential energy before rolling up the inclined plane.
C because the higher the cart rolls on the inclined plane, the less potential energy accumulated.
B because the cart rolling on the inclined plane does not affect the potential energy of the cart.
A because the higher the cart rolls on the inclined plane, the more potential energy accumulated.
Which part has the electrical energy?
Batteries
Electric Wire
Light bulb
If you plan an experiment using two batteries as shown, what is the purpose of the experiment?
