Question

Which example has only potential energy and no kinetic energy? a roller coaster zooming down a hill a child riding their bike a bird flying from a tree a ball sitting on a shelf

Answer 1

Answer: a ball sitting on a shelf

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

Answer 2

D) A ball sitting in a shelf
