Introduction:

Force, Work & Power Relation:

Force is defined as a push or pull capable of changing the state of rest or motion of an object. SI unit of Force is Newton (N).
Work done on an object is the enrgy required by an object to be raised to height h from its initial position. Mathematically, W= (Force required to raise the object) in N $\times$ (Height (h) lifted by the object) in m. SI Unit of Work is N.m or Joules (J).
Power is defined as work done in one second in SI unit. Unit of Power is J/s, W (Watt) or in HP.
