Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I have a question about how balls react on collision while having diffrent mass,

lets say two balls are moving on one dimension, the first ball has the speed of V1, mass of M1, and the other ball has V2,M2.

what will be their speed after the collision?

assuming there are no other forces involved.

It is logical to me that if their mass is the same, the balls will exchange their speed, but I don't know what will happen if the balls will be with diffrent mass.
