Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

What causes a ball thrown in the air to fall to the ground?

A	friction
B	inertia
C	mass
D	gravity

Explanation:

Detailed explanation-1: -A ball thrown upwards falls back towards the surface of Earth due to force of gravity. The force of gravity is a force.

Detailed explanation-2: -The force of friction acts between the two surfaces by opposing the relative motion of one surface over the other. For example, when the ball rolls on the ground, the force of friction acts between the surface of the ball and the surface of the ground.

Detailed explanation-3: -When a ball is dropped from some height, it experiences the force of gravity in downward direction. The force of gravity accelerates the ball with acceleration ‘g’ in downward direction. Thus, the ball start its motion in the same direction as that of the force of gravity, when dropped from some height.
