The correct answer is "the energy of motion." Kinetic energy is the energy possessed by an object due to its motion. To understand this concept, we can think of a moving object like a ball. When the ball is in motion, it possesses energy, and this energy is known as kinetic energy. The formula to calculate kinetic energy is KE = 1/2 * m * v^2, where KE represents kinetic energy, m represents the mass of the object, and v represents its velocity or speed. By plugging in the values of mass and velocity into this formula, you can calculate the kinetic energy of an object.
