The first law of Newton states that an object is at rest unless there is a force that moves it. The force in this case would be the gasoline which would fuel the car and will move it.
Newton's Second Law of Motion
Newton's second law of motion states is that force=mass times acceleration. This image expresses that because the bulldozer has a lot more mass which would end up wrecking the little car which is significantly smaller
Newtons 3rd law of motion states that all forces that interact with each other will end up having an opposite reaction. The result of these two cars crashing will end up pushing them back to where they were originally going.
