Define different units of force.

Solution

Absolute unit of force:
In SI system, the unit of force is newton.
One Newton of force is the force which produces 1 m/sec²acceleration in 1 kg mass.
In cgs system, the unit of force is dyne.
1 dyne is the force which produces 1cm/sec²acceleration in 1 gm of mass.
Gravitational unit of force:
In SI system, gravitational unit of force is kgf (kilogram force).

It is that force which accelerates 1 kg mass with acceleration 9.8 m/s².
