Question

Can the magnitude of the relative velocity of either of two objects be more than the magnitude of the velocities of these objects? Give one example.

Answer 1

Dear Students,

◆ Answer -

Magnitude of relative velocity will be more than velocity of object A and object B when their directions are opposite.

● Explaination -

Relative velocity of object A wrt object B is given by -

vAB = vA - vB

When object B is moving in direction opposite to object A -

vAB = vA - (-vB)

vAB = vA + vB

As vA+vB > vA and vA+vB > vB, magnitude of relative velocity will be more than velocity of object A and object B.

For example,

Magnitude of relative velocity will be more when two bullets are fired in opposite direction.

Thanks dear...
