The physics behind car crashes

Answer 1

There's the conservation of momentum ( p=m*v) in EVERY collision

and depending on the type of collision whether it be "Elastic" or "Inelastic", there's also a conservation of Kinetic Energy (KE=1/2 m*v^2)

Answer 2

Well to start, a car moves due to static friction between the wheels and the ground.

The mirrors in the car use reflection to provide you with images of the things behind you, and also the mirror that says "Objects in mirror closer than they appear" is a convex mirror which was designed to help you see more of what's there.

The engine has to do with thermodynamics and the process of the gas combusting and changing into mechanical energy.

And then electricity is included in how everything works in the car.

The radio has to do with waves and frequencies in order to determine the station.

That's all I can think of for now but there is most likely a lot more physics that go into a car.

Answer 3

The following points should be considered specifically for the case of a car crash:

• The sudden change of velocity implies large forces. These forces can cause damage to the cars and people inside it. (Newton's Second Law)
  
• Total momentum is of course conserved. (Conservation of momentum is closely related to Newton's Third Law.)

Answer 4

energy is conserved no matter how you use it according to the law of conservation of energy which states that energy can not be created or destroyed only transferred

Answer 5

The basic idea here is that the sudden change in velocity requires a large force - in many cases enough to crush the car, or the passengers.

Answer 6

It explains mathematically how velocities (accelerations) change when forces are applied.
