A dropped ball gains speed because
A)its velocity changes.
B)a gravitational force acts on it.
C)of inertia.
D)its nature is to become closer to Earth.

Question

Quizplus · Accepted Answer

A dropped ball gains speed because of the acceleration due to gravity, which is a gravitational force acting on it. The force of gravity causes the ball to accelerate and increase its speed as it falls towards the Earth's surface. Inertia (choice C) plays a role in resisting changes in motion but does not cause the ball to gain speed. The statement in choice D is not accurate; it is not the nature of the ball to become closer to the Earth.
