Newton's first law of motion explains the need for head rests because when a car drives when being in a state of non-motion, the passengers in the car will continue to remain without motion. The force of movement will push the passengers back until they compensate for motion. Since the head is likely to get jerked back quickly during this time, it explains the need for headrests.
Push qnd
An object in motion tends to stay in motion and an object in rest tends to stay in rest unless acted upon by an unbalanced force.
the law of inertia
Newton's first and third laws of motion don't contribute anything to an understandingof Kepler's laws of planetary motion.Kepler's laws can be derived from Newton's law of universal gravitation, along with hissecond law of motion.

The First!
His First Law and Second Law both do.
Isaac Newton, he discovered: -Newton's First Law of motion. -Newton's Second Law of motion. -Newton's Third Law of motion.
It is associated with the law of gravitational pull.
