Expert Answer
- Newton’s first law of motion: According to it, an object acted upon by no net force will remain at rest or continue to move with a constant velocity and zero acceleration.
- Newton’s second law: The rate of change of momentum of an object is equal to the net external force and takes place in the direction in which the net force acts.
- Newton’s third law of motion: To every action force, there is always an equal and opposite reaction force. When object 1 exerts a force on object 2, object 2 must exert a force on object 1 which is equal in magnitude and opposite in direction.
