Relative velocities impact.

  • #1
Hello.

Out of nowhere i started wondering about relativity, I got some question that made me curios.

If we have 2 cars on the road, car A moving at speed 110, car B moving at speed 120 , if car B touched ( hit or tagged ) car A.
Will it be the same impact or the damage done if car A was at speed 30 and car B at speed 40 ?
Considering the two cars are identical.

Im just a second year engineering student, didn't study much physics yet.

The answer is yes. In both cases you could choose a reference frame where one car had speed zero and the other car speed 10.

Motion is relative. There is no such thing as absolute speed.
