Question

define potential energy of an object give an expression for gravitational potential energy​

Answer 1

hey❤

here is ur answer!!

The energy possesed by a body by virtue of its changed position is called potential energy.

It is denoted by symbol U.

Ex : A body is placed ata height above the ground.

Gravitational potential energy :

U = mgh

m= mass of the body.
g = acceleration due to gravity.
h = height of the body

hope it helps uh!!

thanks!!

Answer 2

potential energy is the energy possessed by a body due to virtue of its position.

potential energy is given by

PE=mgh     when h<<<Re

Re=radius of earth

h=height of object

m=mass of object

gravitational PE=-GMm/(R+h)

G=universal gravitation constant
