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 ?

What distance did the stone move ?

Calculated the amount of force (in N) respuird to displace an object by 2 m in the direction of force. Work done in this process is 5kJ.

Identify the incorrect statement(s) among the following (A) If the total displacement of a particle applied by some force is zero. Then the work done by the force on the particle will be zero. (B) Non conservative force will do negative work always (C) Work done by a constant force on a particle which negotiates closed path in round a trip will be zero (D) Work done by a constant

A force of 7 N acts on an object. The displacement is, say 8 m, in the direction of the force (see Figure below). Let us take it that the force acts on the object through the displacement. What is the work done in this case ?

A force of 7N acts on an object. The displacement is, say 8m, in the direction of the force, Let us take it that the force acts on the object throughout the displacement. What is the work done in this case ?

A force F=(10+0.5 x) acts on a particle in the x-direction. What would be the work done by this force during a displacement from x=0 to x=2m (F is in newton and x in metre)
