What is the energy of an object in motion?

A. elastic energy

B. kinetic energy

C. nuclear energy

D. potential energy

In physics, the kinetic energy (KE) of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. In simple words it's B

kinetic

we can eliminate a and c as answers because this has nothing to do with either of them. potential energy is the energy of a still object. kinetic energy is the energy of an object in motion.
