<human>:  How does kinetic energy work?
<bot>: Kinetic energy is the energy of movement. It is the energy of an object that is in motion, such as a car or a ball rolling across the ground. Kinetic energy is directly related to the mass of the object and its velocity. The faster an object is moving, the more kinetic energy it has. In equation form, the kinetic energy of an object with a mass of m and traveling at a velocity of v is equal to one half of the mass multiplied by the velocity squared. Kinetic energy = 0.5 * m * v^2.
