Which of the following represents an example of kinetic energy?

• A. A moving car traveling at $v$ meters per second
• B. A rock positioned at the top of a hill
• C. A battery storing chemical energy
• D. A compressed spring held at rest

Answer: (A)

Verified step by step guidance

1. Understand the definition of kinetic energy: it is the energy an object possesses due to its motion.
2. Identify which options describe objects that are moving, since kinetic energy depends on velocity.
3. Recognize that a moving car traveling at velocity \(v\) meters per second is in motion, so it has kinetic energy.
4. Note that a rock positioned at the top of a hill, a battery storing chemical energy, and a compressed spring held at rest are examples of potential energy or stored energy, not kinetic energy.
5. Conclude that the example representing kinetic energy is the moving car, as it directly involves motion.
