Question

If you stretch back a rubber band and release it, it shoots across the room. What type of energy conversion has occurred?

mechanical to thermal

elastic to chemical

elastic to mechanical

mechanical to elastic

Answer 1

Elastic to mechanical is the energy conversion that occurs. Elastic, the pulling back and stretching of the rubber band, mechanical is the release!

Answer 2

Answer: elastic to mechanical

Explanation: According to the law of conservation of energy, energy can neither be created nor be destroyed. It can only be transformed from one form to another.

Elastic energy is the energy stored as a result of applying a force to deform an elastic object. The energy is stored until the force is removed. When the force is removed,  the object gets back to its original shape.The deformation can involve compressing, stretching or twisting of an object.

Mechanical energy is the energy possessed by a body by virtue of its position and motion.
