Question

A pendulum is released from a high position Because of friction, the pendulum eventually stops swinging Which of the following actions occur as the pendulum stops swinging?

a) Kinetic energy increases

b) Potential energy decreases

c) Kinetic energy remains the same

d) Potential energy remains the same

Answer 1

b) Potential energy decreases

Step-by-step explanation:

The reason why Potential energy decreases here is because you know that if you bounce a ball without applying any force to it, then it falls, and then comes back up, but does it come all the way up to where it was fallen from? NO! So that's why, each time the ball bounces, the potential energy goes down.

Thanks!
