Newton's first law: An object in motion tends to stay in motion and an object at rest tends to stay at rest unless it's acted on by an outside force. An example is this is a ball flying though the air. As the ball encounters air resistance and gravity it slows down. If air resistance and gravity weren't a factor it could potentially fly forever.
Newton's second law: The acceleration of an object produced by a net applied force is directly related to the magnitude of the force, the same direction as the force, and inversely related to the mass of the object. In golf this applies when the force of the club hits the ball propelling it in a direction.
Newton's third law: Every action has an equal and opposite reaction. In golf this can be seen by the club hitting the ball. As the club hits the ball it's the action. When the ball flies away it's the reaction to that.
