Understand the concept of kinetic energy: Kinetic energy is the energy that an object possesses due to its motion. It is given by the formula: , where is the mass of the object and is its velocity.
Identify the options given in the problem: A charged battery, a stretched rubber band, a moving car, and a compressed spring.
Analyze each option: A charged battery stores energy in the form of chemical potential energy. A stretched rubber band and a compressed spring store energy as elastic potential energy.
Recognize that a moving car is the only option where the object is in motion, thus possessing kinetic energy.
Conclude that the correct answer is a moving car, as it is the only option that represents an object with kinetic energy due to its motion.
