Question

Name the kind of force which acts on a stone thrown vertically upward.

Answer 1

1. Everybody present on the surface of the earth is attracted toward the center of the earth due to the force of gravity.
2. When a stone is thrown vertically upwards, the motion of the stone in the upward direction is hindered by gravity.
3. The force of gravity acts in the downward direction and ultimately brings the stone back to the surface of the earth.

Hence, the force of gravity acts on a stone thrown vertically upward.
