A stretched rubber band possesses which form of energy due to its changed shape?
Elastic potential energy
Energy stored in a body because of a change in its shape or configuration (stretching, compressing, twisting) is called elastic potential energy, a form of potential energy.
When a rubber band is stretched, work done on it is stored as elastic potential energy; when released, this energy is converted into kinetic energy as the band snaps back to its original shape.
Gravitational potential energy depends on the height of a body above the ground, not on a change of shape. Sound and thermal energy are not the energy stored because of deformation of the band.
Hence, Elastic potential energy.
