Which of the following is an example of elastic potential energy?
AEnergy of a moving car
BEnergy stored in a compressed spring
CEnergy of a falling stone due to height
DEnergy dissipated by friction
Answer & Solution
Correct answer: B. Energy stored in a compressed spring
A compressed or stretched spring stores elastic potential energy. A moving car has kinetic energy, a raised stone has gravitational potential energy, and friction generally converts mechanical energy into heat.
