Question

1. which location is potential energy the highest in this system? a b c d

Explanation:

Step1: Recall potential - energy formula

The gravitational potential energy is given by $U = mgh$, where $m$ is the mass, $g$ is the acceleration due to gravity and $h$ is the height. For a fixed - mass object in a constant gravitational field, the higher the object, the greater its potential energy.

Step2: Compare heights of points

By observing the figure, we can see that point A is the highest among points A, B, C and D.

Answer:

A
