Compare and contrast potential and kinetic energy. Give two examples that clarify the differences
between the two. What will be an ideal response?
Potential and kinetic are both forms of energy. Potential energy is stored energy that results from
position or state. One example is shown in Fig. 7-1, when an archer draws back a bowstring notched
with an arrow. Or when energy is stored in food molecules. Kinetic energy is the energy of motion, as
when the archer releases the bowstring thereby causing the arrow to fly toward the target, or when
cellular respiration converts the energy in food molecules into the energy of muscle contraction.
