A pendulum bob at its highest point has a certain amount of potential energy. As it falls, what does the potential energy get transformed into? A. kinetic energy only B. potential energy only C. kinetic energy and heat energy D. potential energy and heat energy

Kinetic energy and heat energy

Explanation:

When a pendeleum reaches its highest point, the velocity is zero; however, the acceleration is at its greatest, so the potential energy (pgh) is at its greatest and the kinetic energy is equal to zero (1/2mv^2). However, when falling, the potential energy is converted into kinetic energy because at the lowest point, the acceleration is equal to zero but the velocity is at its greatest. Some energy is lost and converted into heat because when the pendulum comes back up again, it will most likely not be at its highest point.

I hope this helps and makes sense!

idk what the question is about
