Work, Energy & Power
Work:
The product of force acting on a body and displacement of a body in the direction of force is called work. It is a scalar quantity. Its SI unit is Joule and CGS unit is erg. Work(W) = Force x displacement in the direction of force W = F x d
Factors affecting the Work:
- Magnitude of force
- Direction of force
- Displacement of the object due to force
Energy Ability to do work is called energy.
It is a scalar quantity. SI unit of energy is Joule.
