Answer: a ball sitting on a shelf
Step-by-step explanation:
Kinetic energy is the energy possessed by an object by virtue of its motion.
Potential energy is the energy possessed by an object by virtue of its position.
a) a roller coaster zooming down a hill possess kinetic energy as it is in motion.
b) a child riding their bike possess kinetic energy as it is in motion.
c) a bird flying from a tree possess kinetic energy as it is in motion.
d) a ball sitting on a shelf does not possess kinetic energy as it is not in motion and possess potential energy only.
Thus a ball sitting on a shelf has only potential energy and no kinetic energy
