Question
When a rubber band is stretched and then released, what form of energy does it have?
- Kinetic energy
- Potential energy
- Kinetic + Potential energy
- Sound energy
Hint:
Kinetic energy is the energy that a body possesses by virtue of being in motion.
Potential energy is the stored energy that depends upon the relative position of various parts of a system.
The correct answer is: Kinetic energy
When a rubber band is stretched and then released, it possesses potential energy.
- The energy used to stretch a rubber band is stored in the material's elasticity.
- It has a bounce-back effect, which is brought on by a transient mechanical deformation.
- Anything that has been temporarily distorted yet has the capacity to change when work energy has influenced it.
- Elastic potential energy is the name given to this stored energy.
