What is relative motion and relative velocity?

1.	What is relative motion and relative velocity?
Answer» What is Relative Motion? The concept of reference frames was first introduced to discuss relative motion in one or more dimensions. When we say an OBJECT has a certain velocity, then this velocity is with RESPECT to some frame that is known as the reference frame. Relative Velocity The relative velocity of an object A with respect to object B is the RATE of CHANGE of position of the object A with respect to object B. If VA and VB be the velocities of objects A and B with respect to the ground, then The relative velocity of A with respect to B is VAB = VA – VB The relative velocity of B with respect to A is VBA = VB – VA

What is Relative Motion?

The concept of reference frames was first introduced to discuss relative motion in one or more dimensions. When we say an OBJECT has a certain velocity, then this velocity is with RESPECT to some frame that is known as the reference frame.

Relative Velocity

The relative velocity of an object A with respect to object B is the RATE of CHANGE of position of the object A with respect to object B.

If VA and VB be the velocities of objects A and B with respect to the ground, then

The relative velocity of A with respect to B is VAB = VA – VB

The relative velocity of B with respect to A is VBA = VB – VA
