Question

which of the following is an example of kinetic energy being transformed into potential energy? c. a light bulb turning on in a lamp. d. a person sitting at the top of a slide. a. a roller coaster car stopping at the end of the ride. b. a pendulum swinging upward after it has swung down.

Explanation:

Kinetic energy is energy of motion and potential energy is stored energy. A pendulum swinging upward slows down (losing kinetic energy) and gains height (increasing potential energy). A roller - coaster car stopping loses kinetic energy but doesn't gain potential energy in the context of this question. A light - bulb turning on converts electrical energy to light and heat, not kinetic to potential. A person sitting at the top of a slide has potential energy already, not a transformation from kinetic.

Answer:

B. A pendulum swinging upward after it has swung down.
