The motion of an object under the influence of gravitational force due solely to the earth is referred to as:

The motion of any object caused solely by gravity is referred to as free fall. During free fall, the object's direction of motion will not change. The magnitude of the object's velocity, on the other hand, will change due to the earth's gravitational pull.

The motion is called free fall when an object moves with a constant acceleration under the only effect of gravity at that location.

When an object falls towards the earth, it experiences acceleration. This acceleration is called acceleration due to gravity or acceleration due to the gravitational force of the earth because it is caused by the earth's gravitational pull.
