Thu, 24 March 2005 06:54 FWDboy wrote on Thu, 24 March 2005 17:42 People always seem to forget that when two cars collide the energy of the collision is spread between BOTH vehicles rather than just being absored by the one vehicle while the other vehicle is oblivious to what goes on. So in answer to your question, hitting another car at 50km/h when the other car is going 50km/h towards you is about the same as you hitting a wall at 50km/h - in regards to the ENERGY of the impact (edit)that you experience(/edit). Overall the forces involved (for one car) are the same, the big difference is the impulse of the collision, one will dissipate the energy over time (a smaller force over a longer period) and the other will result in a larger force being exerted on your body in a shorter period of time. The same energy is transferred to your body, and the amount of force your body experiences should be the same, it's just that there is more destructiveness in large impulse forces. THANKYOU hang on, dont you mean hitting another car also travelling 50km/h is the same as hitting a wall at 100km/h? [Report message to a moderator]
