Newton`s Second Law

... Newton’s First Law: An object at rest remains at rest, and an object in motion remains in motion with the same speed and direction (maintains its velocity) unless it experiences an unbalanced force. Example: A soccer ball resting on the grass remains motionless until a force is applied (a kick). Th ...
