 How Newton's 1st Law of Motion Is Applied to Basketball ​ Newton's first law of motion applies to basketball when the ball is rolling across the court or just sitting there at rest. It applies because the ball with keep rolling at a constant speed in a straight line unless a net force acts on it or the ball will sit there at rest unless a net force acts on it. This is caused by gravity and inertia because they make a basketball roll across the floor.
