What is the relationship between gravity and kinetic energy when an object falls freely?

• Gravity increases kinetic energy as the object falls.

• Gravity decreases kinetic energy as the object falls.

• Gravity has no effect on kinetic energy.

• Gravity converts kinetic energy to potential energy.
