Relative speed of two bodies moving in opposite direction with speed u and v m/s.

Relative speed of two bodies moving in same direction with speed u and v m/s: where (u>v)

Statement-1 : The relative velocity between any two bodies moving in opposite direction is equal to sum of the velocities of two bodies. Statement-2 : Sometimes relative velocity between two bodies is equal to difference in velocities of the two.
