Newton's First Law
By: Jorge Navarro
Definition
States that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
The balls stay at rest until one of them hits the outside. Then other balls are in motion because of the first ball that was realest. But if no movement is made all the balls well stay at rest.
The football is at rest when its sitting on kicking tee. When its in motion is when they kick it off the tee and they make physical contact. It will still be in motion when its in the air because it will be still moving or spinning.
