the image shows a pendulum that is released from rest at point a. shari tells her friend that no energy transformation occurs as the pendulum swings between point b and point d. what is the best response that sharis friend could make? she could agree with shari because the pendulum is at the same height and would have the same gravitational potential energy at both positions. she could agree with shari because the pendulum has the same amount of mechanical energy throughout its swing. she could disagree with shari because the pendulum converts kinetic energy into gravitational potential energy, then back into kinetic energy. she could disagree with shari because the pendulum converts gravitational potential energy into kinetic energy, then back into gravitational potential energy.

Answer

Brief Explanations:

When a pendulum swings between two points at different heights, energy transformation occurs. At the higher - points (like B and D), it has more gravitational potential energy. As it moves towards the lower - point (like C), gravitational potential energy is converted into kinetic energy. Then as it moves back up, kinetic energy is converted back into gravitational potential energy. Shari's statement that no energy transformation occurs between B and D is incorrect.

Answer:

She could disagree with Shari because the pendulum converts gravitational potential energy into kinetic energy, then back into gravitational potential energy.
