Mathematically, work is defined as the product of froce and displacement through which force acts. If F is the applied force, 'S' is the displacement in the direction of applied force and W is the work done, then : Work done = Force xx Displacement through which force acts. W = F xx S The SI unit of work is Joule (J) and cgs unit is erg. 1 J = 10^(7) erg. 6000 J of work is done to move a rock 25 m. How much force was applied ?
