Question

select the correct answer. which sentence describes an object that has kinetic energy? a. a seagull sits on top of a fence post. b. a beach ball is round. c. a radio has batteries with stored chemical energy. d. a boat sails across the ocean.

Explanation:

Kinetic energy is the energy of motion. A boat sailing across the ocean is in motion, so it has kinetic energy. A seagull sitting is at rest (potential energy due to position), a beach - ball's shape has nothing to do with kinetic energy, and a radio's battery has chemical potential energy.

Answer:

D. A boat sails across the ocean.
