ABSOLUTE GRAVITATIONAL POTENTIAL ENERGYTOPIC

INDEX ……… ENERGY POTANTIAL ENERGY ABSOLOTE GRAVITATIONAL POTENTIAL ENERGY DEFINITION ZERO POTENTIAL DEPENDENCE FORMULA DERIVATION UNIT EXAMPLE

ENERGY…….. The ability of body to do work is known as energy.

POTENTIAL ENERGY…... The energy of body due to its position.

DEFINITION…….. The potential energy possessed by a body at a certain height in a gravitational field with respect to reference point of zero potential is known as absolute potential energy

ZERO POTENTIAL…….. The actual potential of the surface of earth taken as reference point.

DEPENDENCE……… it depends on three factors :

mass of object acceleration due to gravity height of object

FORMULA………

DERIVATION…………

•Similarly

•GMem

•GMem•As •So; GMem•As •So; GMem

• As work done is against the gravity so value of g will be negative.

UNIT…………

EXAMPLE………. Aeroplane is an example of gravitational potential energy.
