Praxis 5511 Practice Question
Best example of kinetic energy?
Correct Answer: A
Rationale: Kinetic energy refers to the energy an object possesses due to its motion. A spinning top (A) is a prime example, as it is actively rotating, showcasing its kinetic energy. In contrast, a stretched rubber band (B) stores potential energy that is released when it snaps back, but it is not in motion itself. A book on a shelf (C) is stationary and therefore has no kinetic energy; it possesses potential energy due to its position. A person on a ladder (D) may have potential energy based on their height, but unless they are moving, they do not exhibit kinetic energy.
