    The product of force and displacement is __________.

    The product of force and displacement is "________" .

    One joule is the product of force of 1N and displacement of ___________.

    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. How much work is done by a person who uses a force of 50 N to move a grocery buggy 10 m ?
