A system has basic dimensions as density [D], velocity [V] and area [A]. The dimensional representation of force in this system is :

In a new system of units, the fundamental quantities mass, length, time are replaced by acceleration 'a', density 'rho', and frequency 'f'. The dimensional fromula for the force in this system is

If the velocity of light c, Planck's constant h and gravitation constant G are adopted as fundamental units of a system, the dimensions of force in the system would be :

If area (A) velocity (v) and density (rho) are base units, then the dimensional formula of force can be represenited

If area (A) velocity (v) and density (rho) are base units, then the dimensional formula of force can be represenited

If area (A) velocity (v) and density (rho) are base units, then the dimensional formula of force can be represenited

A system of particles is free from any external force vec v and vec a be the velocity and acceleration of the centre of mass, then it necessarily follows that :
