Question
Define absolute units of force in CGS as well as the SI system.

Solution
Absolute unit of force in the CGS system is dyne and in SI system is Newton (N).
One dyne: When the body of mass 1 gram moves with an acceleration of 1 cms−2, then the force acting on the body is called one dyne.
1 dyne = 1 g cms−2
One Newton: When a body of mass 1 kg moves with an acceleration of 1 ms−2, then force acting on the body is said to be one newton.
OR
That force is said to be one newton, which producers an acceleration of 1 ms−2 in a body of mass 1 kg.
1 N = 1 kg ms−2
