Question

select the frog that has the greatest potential energy.

Explanation:

Step1: Recall potential - energy formula

The gravitational potential energy formula is $U = mgh$, where $m$ is mass, $g$ is the acceleration due to gravity, and $h$ is the height. Assuming the mass of the frogs is the same and $g$ is constant, potential energy depends on height.

Step2: Compare heights

Frog 1 is at the highest position among the three frogs. Since $U\propto h$ (when $m$ and $g$ are constant), the frog at the greatest height has the greatest potential energy.

Answer:

Frog 1
