Question
What are the three Newtons Laws of Motion.

Answer

Newton's First Law of Motion : Every body continues to be at rest or in motion until or unless it is compelled by an external force.
Newton's Second Law of Motion : The rate of change of momentum of a body is directly proportional to the force applied and in the same direction as the force is applied.
Newton's Third Law of Motion : To every action there is equal and opposite reaction.
