Question

Draw position time graphs related to
relative velocity
a)The body B is moving behind the body
A and VA=VB
b)The body B is moving behind the body A
and VA>VB
c)The body B is overtakes the body A at
the time t. i.e VB>VA

Answer 1

Relative velocity : It is the difference between the velocities of two objects.

Let the velocity of object A = Va

and the velocity of object B = Vb

Then, the relative velocity of object A with respect to object B

Vab = Va -Vb

Here, Va = Motion of object

and Vb = Frame of reference

And, the relative velocity of object B with respect to object A

Vba = Vb - Va

Here, Vb = Motion of object

and Va = Frame of reference
