i want to know the force of 3.0 kg weight dropped from 1.0 meter height for breakage testing purpose

The force exerted depends upon what it hits, and how long it remains in contact. All you can predict with the information you provided is the IMPULSE, which is (average force)*(time)

If you want to apply a known force in compression, you will need something like a calibrated vice. For breakage in tension, there are tensile test machines.
