The vector difference between the absolute velocities of two bodies is called their relative velocity. The concept of relative velocity enables us to treat one body as being at rest while the other is in motion with the relative velocity. This jormalism greatly simplifies many problems. If `vecv_(A)`is the absolute velocity of a body A and `vec_(B)`that of another body B then the relative velocity of A in relation to B is `vec_(AD)=vecV_(A)-vecv_(B)` and `vecv_(BA)=vecv_(B)`-`vecv_(A)`.
The principle follows here is that the relative velocity of two bodies remains unchaged if the same additional velocity is imparted to both the bodies. A simple way of carrying out this operation is to be represent the velocities in magnitude and direction from a common point. Then the line joining the tips of the vectors represents the relative velocity
Q A train A moves to the east with velocity of 40 km/hr and a train B moves due north with velocity of 30 km/hr. The relative velocity of A w.rt. B is

If vecv_(A) is the absolute velocity of a body A and vec_(B) that of another body B then the relative velocity of A in relation to B is vec_(AD)=vecV_(A)-vecv_(B) and vecv_(BA)=vecv_(B) - vecv_(A) .

Then the line joining the tips of the vectors represents the relative velocity Q A river is flowing from west to east at a speed of 5 m/s. A man on the south bank of the river, capable of swimming at 10 m/s in still water, wants to cross the river without drifting, he. should swim

Problems on Relative Velocity of Rain and Woman

Relative Angular Velocity

Block B moves to the right with a constant velocity v_(0) . The velocity of body A relative to B is :

Assertion: Relative velocity of A w.r.t B is greater than the velocity of either, when they are moving in opposite directions. Reason: Relative velocity of A w.r.t B=vecv_(A)-vecv_(B)
