When a rubber band is stretched it has what kind of energy?

Answer 1

Potential energy is converted into kinetic energy.

Answer 2

When you stretch and hold the rubber band it has potential energy. When you release a stretched rubber band the potential energy is transformed into kinetic energy.

The same thing applies if you climb a ladder with a rock in your hand. The rock has acquired potential energy in its journey up the ladder. If you were to release it at the top and let it fall, you would be releasing the potential energy of the rock, converting it to kinetic energy on it's trip down.

Answer 3

The rubber material has been distorted and/or compressed and this has required energy to be put in, depending on the exact configuration, but consider a model airplane with a rubber band driving the propeller. You wind the propeller with your finger, it is light at first but gets stiffer as it tightens up. You are putting energy into it, and that is energy stored in the rubber band, and that is what is meant by potential energy.

Answer 4

Stretching the elastic requires work to be done against the force of the rubber band. Energy (work) equals force times distance. When the band is stretched the energy is stored as potential energy in the band. It can then be used to propel a projectile (as in a catapult) to transfer the energy to the kinetic energy of the projectile, KE = half x mass x velocity-squared.

Answer 5

elastic potential energy:]
The rubber band has strain energy, equal to the band 1/2 spring constant times the square of the stretch. This is converted to kinetic energy when released.

Answer 6

Potential energy held in the form of stretched and/or twisted chemical bonds.

Answer 7

When a rubber band is wound up, as in a model airplane, mechanical energy is stored in it as elastic potential energy. This can be released and transformed back to mechanical energy.

Answer 8

Elastic and potential energy.
Elastic potential energy.

Answer 9

When a rubber band is stretched, it has potential energy. Any type of stored energy is known as potential energy.
