@6394 .. i know :P muhje pataa hai :P
GRAVITATIONAL POTENTIAL ENERGY is the amount of energy stored in a body at a particular height ..
FORMULA :: P.E = m*g*h
mass, acceleration due to gravity(10 m/s2), and height
eg wen u stand on a flight of stairs of 10m then ur
PE = 60kg * 10 * 10
=6000J
wen u stand at the bottom of the stairs (ground level) your PE = 60 * 10 * 0 = 0 J
so least PE is at the bottom .. ;)
