What are newtons 3 laws of motion?(an easy definition that would be fit for the lc)

Newton’s First Law of Motion – every object will remain in a state of rest or travelling with a constant velocity unless an external force acts on it.

Newton’s Second Law of Motion – the rate of change of an object’s momentum is directly proportional to the force which caused it.

Newton’s Third Law of Motion –  if an object A exerts a force on an object B, then object B will exert an equal but opposite force on object A.
