Question: What is the gravitational potential energy of an object at height h?

Options:

1. PE = mgh
2. PE = 1/2 mv^2
3. PE = Fd
4. PE = mv

Correct Answer: PE = mgh

Solution:

The gravitational potential energy of an object at height h is given by PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
