Question

if you squeeze a foam pillow, what kind of energy are you increasing in the foam?
a. nuclear energy
b. sound energy
c. elastic energy
d. chemical energy

Explanation:

When you squeeze a foam pillow, you are deforming the foam. Elastic energy is the energy stored in an object when it is deformed (stretched or compressed) and can return to its original shape. Nuclear energy is related to the nucleus of atoms, sound energy is related to vibrations that cause sound, and chemical energy is stored in chemical bonds. Since squeezing a foam pillow (a deformation that can reverse) is about elastic deformation, the energy involved is elastic energy.

Answer:

C. Elastic energy
