Question

Which of the following objects have kinetic energy? Check all that apply. a book lying on a shelf a book inside a moving vehicle a running cat an unmoving rock in the middle of the road a picture hanging on a wall a falling meteorite

Answer 1

The correct answers are a moving vehicle, a running cat, a falling meteorite. This is because kinetic energy applies to things that are in motion and is dependent on mass and speed. All of the choices listed above have mass and speed. Hope this helped.

Answer 2

The right options are;

a book inside a moving vehicle

a running cat

a falling meteorite

Kinetic energy is the form of energy that an object or a particle has due to its motion (horizontal or vertical). An object gains kinetic energy when work is performed on it by putting a net force. This makes the object to speed up and acquire kinetic energy. Any object or particle that is moving is using kinetic energy; a thrown baseball, a running cat, a book inside a moving vehicle and a falling meteorite are all examples of kinetic energy at work.
