Question

which situation would be appropriate for the transfer of energy from kinetic energy into gravitational potential energy? (1 point)

a car accelerating from a stop on a flat road

a ball being dropped off of a cliff

a skateboarder going down a ramp and speeding up

a ball being launched from the ground to its apex

Explanation:

Kinetic energy is energy of motion ($KE=\frac{1}{2}mv^{2}$) and gravitational potential energy is $PE = mgh$ (where $h$ is height). When an object moves upward against gravity, its speed (kinetic energy) decreases and height (gravitational potential energy) increases. A ball launched from the ground to its apex is moving upward, losing speed and gaining height, so energy is transferred from kinetic to gravitational - potential. In other options, energy is either not transferred in this way (car on flat road) or is transferred from gravitational - potential to kinetic (ball dropped, skateboarder going down ramp).

Answer:

a ball being launched from the ground to its apex
