◆ Work , Power and Energy ◆
Work :-
――――――――
Work is said to be done when a force acting on a body produces Displacement in it in the direction of force.
W = F × S
Power :-
―–――――――
The rate of doing work is called power.
Power = Work/Time, 1 watt = 1joule/1 second.
OR , It is also defined as the rate of supplying energy :
P = E/t
Energy:-
―――――――――
The ability of doing work is called energy.
That is, the amount of energy possessed by a body = The amount of work done.
