Answer

Answer:

The gravitational potential energy equals the work needed to lift the object.

Explanation:

Step1: Recall gravitational - PE formula

$PE_g=mgh$, where $m$ is mass, $g$ is gravitational acceleration, and $h$ is height.

Step2: Recall work formula

$W = Fd$, and for lifting an object near Earth's surface $F = mg$ and $d=h$. So $W = mgh$.

Step3: Compare formulas

Since $PE_g=mgh$ and $W = mgh$, the gravitational potential energy equals the work needed to lift the object.
