Which produces more force: driving into a very massive concrete wall with no "give," or having a head-on collision with an identical car moving toward you at the same speed?

Question

Quizplus · Accepted Answer

Both scenarios involve the same momentum and speed, so they will produce the same amount of force. The force would be equal in both cases, but the effects on the car and the driver would differ; in the case of the car collision, the force would be distributed over both cars, while in the case of the wall impact, the force would only be experienced by the single car.
