UP AHEAD: NEWTON'S LAWS
Now that I think about it, I'm currently performing Newton's 1st Law-
By coasting in the car without pressing on the brake, I'm showing inertia, or the tendency of an object to keep doing what it's doing. My car was moving before I let off the brake, so it has a tendency to keep moving. Eventually, however, friction will slow me down.
Newton's Second Law, F=ma, states that the force of something is proportional to both the mass and acceleration of a moving object. My car's acceleration was increasing before I crashed, so the net force of the crash was larger than if I wasn't speeding.
It seems that I'm being arrested, but at least I get to talk about Newton's Third Law!
Newton's 3rd law of motion states that for every action there is an equal and opposite reaction. With every step I take towards the car, the force of my feet pushing forward is matched by the force of the asphalt pushing against my feet.
