Question

A pendulum has 991 J of potential energy at the highest point of its swing. how much kinetic energy will it have at the bottom of its swing?

Your Answer:
Answer:
units:

Answer 1

991 J

Explanation:

At the highest point, an object has maximum potential energy and no kinetic energy. And at its lowest point, an object has maximum kinetic energy and no potential energy. All of the potential energy it had was converted into kinetic.

Answer 2

991 J

Explanation:

At the bottom of the swing all of the potential energy has been converted to kinetic energy (assuming a lossless system).
