Multiple Choice
Which of the following is an example of ?
A
A rock resting at the top of a hill
B
A moving car traveling down the road
C
A stretched bow ready to shoot an arrow
D
A battery storing electrical energy

Verified step by step guidance1
Understand the definition of kinetic energy: it is the energy an object possesses due to its motion.
Identify which options describe objects that are moving, since only moving objects have kinetic energy.
Analyze each option: a rock resting at the top of a hill is not moving, so it has potential energy, not kinetic energy.
A stretched bow stores elastic potential energy, and a battery stores chemical potential energy, so neither represents kinetic energy.
A moving car traveling down the road is in motion, so it has kinetic energy, making it the correct example.
