Question

If an object is raised four times as high, how is its gravitational interaction (potential) energy affected?

Answer 1

See below.

Explanation:

Let's assume that the body previously was at height h from the ground.

If the body is raised four times higher, then height = 4h.

The Initial Potential Energy = mgh
The Final Potential Energy = mg * 4h = 4mgh.

So, The Potential energy will increase by 4 times.
