Which of the following is an example of potential energy? (2 points) a. a basketball sitting on a shelf b. a dog running across a field c. a bowling ball rolling down a lane d. a teenager riding their bike

The correct answer is (a).

Explanation:

The potential energy is due to the position of the object.

The kinetic energy is due to the motion of the object.

In the case of a basketball sitting on a shelf, the basketball posses the potential energy due to some height.

In the case of a dog running across a field, a dog has kinetic energy due to its motion.

In a case of a bowling ball rolling down a lane, there is kinetic energy due to the motion of the bowling ball.

In the case of a teenager riding their bike, there is kinetic energy due to the motion of the bike.

Therefore, the correct answer is (a).

it about 600 mph from what i calculated
