Question

At what point is its PE a maximum? 1. midway between the highest and lowest points 2. at the highest point 3. at the lowest point 4. The PE does not change.

Answer 1

Answer:

2. at the highest point

Explanation:

For a generic object, the PE (gravitational potential energy) is defined as

PE = mgh

where

m is the mass of the object

g is the gravitational acceleration

h is the height of the object with respect to the ground

From the formula, we see that PE is maximum when h is maximum: so the PE is maximum when the object is at the highest point.
