poizon [28]

Explanation:

Gravitational potential energy is the energy of body due to its position in the gravitational field.

Whereas chemical potential energy is the energy within the chemical bonds of a substance.

For example, when we eat an apple then we get energy in our body so, it is the chemical potential energy stored in the apple.

Items sorted on the bases of gravitational potential energy and chemical potential energy are as follows.

Gravitational potential energy:

  • a ball thrown up in the air.
  • a stone rolling downhill.
  • water stored in an overhead tank.

Chemical potential energy:

  • liquid petroleum gasoline used in cars.
  • apples that people eat.
  • firecrackers that people set off.
