Question

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

Answer 1

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
