i know the parallelogram law of forces.but is there any difference between parallelogram law of force and velocities?

Putting it simply, velocity has two parts - speed and direction. As such the parallelogram law may be used to add and subtract velocities.

The "parallelogram law" works for anything vector valued ( that is having magnitude and direction ) such as forces and velocities.
You say that you know the one for forces. It is the same for velocities.

No there is not.
The parallelogram law is generally true for the addition of vectors. Physical quantities such as force, velocity, acceleration, magnetic and electric field and momentum all behave as vectors.
