As gravity makes an object fall down toward the ground, energy becomes kinetic energy.

a. chemical
b. electromagnetic
c. potential
d. thermal

Option (C) is the correct answer.

Explanation:

Potential energy is the energy possessed by an object due to its position.

Mathematically,      P.E = mgh

where              m = mass

                        g = gravitational constant

                        h = height

For example, when a ball is at rest then it means it has potential energy.

Whereas kinetic energy is defined as the energy possessed by an object due to its motion.

For example, when the ball starts to move from its resting position then the ball gains kinetic energy.

Thus, as gravity makes an object fall down toward the ground, potential energy becomes kinetic energy.
