What are the three laws of motion?
The three laws of motion were introduced by S. Isaac Newton hence they are also called Newton’s laws of motion. Newton’s first law of motion says that a moving body will continue to move and a body at rest will always remain at rest as long as they are not affected by any amount of external force. Newton’s second law of motion says that the change in momentum of a body with respect to time is always equal to the applied force on a body. Newton’s third law of motion says that for every action force acting on a body in a given direction there exists a reaction force acting on the same body with the same amount of force but opposite in direction.
