# HOW NEWTON'S 1ST AND SECOND LAWS AFFECT  A CAR'S MOTION

### BY: Xan Wright, Andrianna Pikarsky, Drake Cross, Grayson Jenne'

NEWTON'S 1ST LAW

Once our car was pushed, it kept moving until the material and the friction of that material of the floor, though as smooth as it is, affected the wheels of the car , therefore making it stop.  ( Balanced Forces were involved)

NEWTON'S 2ND LAW

Since the car is made of stainless, it didn't need that much of a push to get it going. Since it is thin, it doesn't have a lot of mass, but the weight is greater than the mass.          ( Unbalanced Forces were involved)

NEWTON'S 3RD LAW

This means that for every force there is a reaction force that is equal in size, but opposite in direction. That is to say that whenever an object pushes another object it gets pushed back in the opposite direction equally hard. ( Balanced Forces were involved)

Below is our graph for our car's movement.

When two cars crash together, newton's laws begin to take place. Newton's First Law affects it because both cars were moving at a constant speed until they hit each other and the speed was to great for the car to stop.

Newton's Second Law takes place when the car's weight and mass propel the car forward since mass and weight move because of the sudden impact and from the speed it was traveling at since they were traveling at a constant velocity.

Newton's Third Law takes place when the cars impact each other, if one was traveling faster than the other, it pushes the one traveling slower back a small distance, or large distance depending on the mass and weight of the slower vehicle.
