Question

Define potential energy of an object. Give an expression for gravitational

potential energy​

Answer 1

Answer:

The energy possesed by a body by virtue of its changed position is called potential energy. ... Ex : A body is placed ata height above the ground. Gravitational potential energy : U = mgh. m= mass of the body.

Answer 2

Answer:

To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.

Gravitational potential energy is energy an object possesses because of its position in a gravitational field. ... Since the force required to lift it is equal to its weight, it follows that the gravitational potential energy is equal to its weight times the height to which it is lifted. PE = kg x 9.8 m/s2 x m = joules.
