Work
When a force acts on an object and the object actually moves in the direction of force, then the work is said to be done by the force.
Work done by the force is equal to the product of the force and the displacement of the object in the direction of force.
If under a constant force F the object displaced through a distance s, then work done by the force
W = F * s = F s cos θ
where a is the smaller angle between F and s.
Work is a scalar quantity, Its S1 unit is joule and CGS unit is erg.
∴ 1 joule = 107 erg
Its dimensional formula is [ML2T-2].
