Answer:
B. motion
Step-by-step explanation:
Kinetic energy is the energy that an object possesses by virtue of its motion. The amount of kinetic energy that an object has depends on its mass and velocity, and is directly proportional to the square of its speed. As an object moves faster, its kinetic energy increases. Conversely, when an object slows down or comes to a stop, its kinetic energy decreases. Kinetic energy is an important concept in physics and is used to describe many different types of motion, from the movement of subatomic particles to the motion of planets and stars.
