Answer 2

Answer:

"Anything which is moving will keep on moving if there is no external force acting on it"

For example a ball rolling in a playground eventually stops due to "friction"

Friction is the force which opposes the relative motion between two surfaces in contact

here the ball is in contact with the ground and friction opposes the motion and stops the ball

Therefore moving objects are opposed by force of friction.
