Write a paragraph of no less than five sentences explaining how Newton's First Law of Motion supports people's need to wear seat belts when riding in a moving car. Remember to use proper grammar and mechanics when writing your paragraph.

Newton's first law can be taken to mean that if something is moving it tends to keep moving. if at rest it tends to stay at rest.

so, in a car, you and the car are both moving, say at constant speed. Now you're not actually connected to the car as in clamped to it, not yet at least. You're simply sitting in it at rest with respect to it.

but, someone slams on the brakes for whatever reason. The car slows down/stops. what do you do? well, you would keep going. and moving a few feet in a car can be dangerous, esp if you're moving at high speed. Unless of course you're clamped to the seat, and the seat is clamped to the car and the car is clamped together. then when the car brakes, yes you'll feel the braking effect, but the belt will restrict your movement, keeping you safe, if shocked and bruised.
