Question

In the case of a swinging pendulum, Potential Energy is greatest when ____.

Answer 1

The correct answer is:

A. the pendulum ball is at its highest points away from a surface.

Explanation:

the potential energy of an object is given by

$U=mgh$

where m is the mass of the object, g is the gravitational acceleration, and h is the height of the object from the ground. Looking at the formula, we see that the potential energy is higher when h is higher, therefore when the pendulum ball is at the highest point away from the surface.

Answer 2

I am almost 100% positive the answer is A.
