Question

explain the relative velocity and its two cases​

Answer 1

The velocity of an object A relative to another object B is the velocity that object A would appear to have to an observer moving with B. Really what we are measuring in all of these cases is the velocity relative to an observer. ... Figure 1: Relative velocities of trains A and B and the platform.

Answer 2

Answer: Defination of Relative velocity:

• The difference of two velocity vectors can be termed as relative velocity.
• It can also be velocity of an object with respect to another.
• Mathematically we can say that relative velocity is vector difference between two velocities.
• Cases 1 : Person walking on treadmill
• Case 2 : Person running inside a moving train and other watching from outside.
