Gravitation and the law of motion could not explain every- thing.

My brother and I were watching a movie which prompted a discussion about the laws of motion.

It was gravity she would be working with again, and the three laws of motion: nothing more involved.

According to Newton's laws of motion, all forces have both magnitude and direction.

That led him to formulate the laws of motion, helped perhaps by an apple.

The laws of motion only apply when the player hits the ball.

Newton's laws of motion are rules for how things move.

It is an example of Newton's third law of motion.

He is best known for his laws of planetary motion.

In particular, dynamics is mostly related to Newton's second law of motion.
