What happen to the people inside a car during collision and the laws apply
The law of conservation of momentum says the center of mass of a system will always continue with the same velocity unless something outside the system acts on it with a force. [ That person has a kinetic energy, and the law of conservation of energy says it must go somewhere, can't just disappear in a crash.
So if the car hits a brick wall, it stops. However, the passenger will continue to move under conservation of momentum until a force stops him. Without a seatbelt or airbag, the force is determined by the mass of the passenger times his rate of deceleration (negative acceleration) upon
hitting the interior of the car (dashboard, etc.). Dashboards don't give much so deceleration is very fast, thus the force will be high. This produces what's known as mechanical shock, damaging the body.
