Question

when only the force of gravity is acting on an object, we say that the object is in centripetal force terminal velocity free fall projectile motion

Explanation:

The definition of free - fall is when only the force of gravity acts on an object. Other options like centripetal force is related to circular motion, terminal velocity is the constant speed when air resistance equals gravitational force, and projectile motion involves an object moving under gravity after being launched.

Answer:

C. Free Fall
