Anything that is elastic has potential energy until it returns to its original shape. This elastic potential energy calculator makes it easy to determine the potential energy of a spring when stretched or compressed. The bungee cord is elastic in nature. During bungee jumps, gravitational potential energy is converted to elastic potential energy. Notify me of follow-up comments by email. Kinetic energy is energy in an object because of its motion. When a stretched spring is compressed or extended, we experience a force that is equal to the force applied by us in the opposite direction. Elastic means that an object will return to its original shape when the force is removed. The main types of potential energy contain the gravitational potential energy of the body, elastic potential energy of a stretched spring, and the electric potential energy of an electric charge in the electric field. Anything elastic will gain EPE when its shape is forced to change. Examples: An object possessing mechanical energy has both kinetic and potential energy , although the energy of one of the forms may be equal to zero. Examples of Elastic Collision.
