Work done = force × displacement , W = F s

=================================================

Potential energy = mgh , m = Mass of the object , h = displacement (height) , g = acceleration due to gravity.

=======================================================

Kinetic energy = 1/2 m v² , m = Mass of the object , v = velocity of the object.

========================================================

Potential energy + Kinetic energy = constant.

=========================================================

Power = work/time , P = W/t

=======================================================

1 W = 1 J s-1

========================================================

1 kW h = 3.6 × 10⁶ J
