Which of the following is an example in which kinetic energy is converted to potential energy?
O A. A rock falls down a cliff.
OB. A match burns.
OC. A spring is stretched.
OD. A light bulb glows brightly.
Kinetic energy is the energy of motion, potential energy is stored energy. The motion of stretching the spring is kinetic, the energy it has before it's released is potential.
