Car collisions happen everyday all over the world just like how physics is used every single day all over the world. Physics has a big part in accidents involving vehicles due to the force, momentum, acceleration and collision that occurs. The force which cars are brought upon each other depends on how great the acceleration is of the moving vehicle. The faster the car is moving, the greater the force will be as it hits the other car. The amount of force that accidents are caused by are largely dependent on Newton's laws. Objects in motion will stay in motion, therefore when a car is moving towards the other and crashes into it, it's because while the vehicle is moving at a high speed it's hard to come to a complete stop before the collision into the other.
