It just depends on how quickly it stops. In some crashes the vehicle may go on out of control for some distance, in head-on crashes it will stop very quickly
True
Kinetic Energy is energy that is dissipated in a crash.
Kinetic energy and gravity both act on a crash test dummy kinetic energy moves it forward whilst gravity pulls it back onto the ground
Momentum, kinetic energy

No, it is 4 times as great. Looking at the equation for kinetic energy: E=0.5 x m x v x v Where E=kinetic energy m = mass of vehicle v = velocity of vehicle If the vehicle weighs 1000 kg and is traveling at 10 m/s the kinetic energy possessed will be 1000 x 10 x 10 = 100,000 joules Whereas if the same vehicle is traveling at 20 m/s it would be 1000 x 20 x 20 = 400,000 joules. In other words, the vehicle possesses four times as much energy.
Kinetic energy is "moving energy". A car moves, it has kinetic energy. In the case of a car crash the energy is released-->smash/bang!!!

Yes. For example, if two moving objects crash, the kinetic energy gets released as heat energy.
No

true
There are two collisions in a crash. The first collision is when the vehicle strikes the object and the second when the unrestrained occupants strike the interior of the vehicle.
