The form of energy associated with the motion of an object is known as kinetic energy. It is calculated using the formula KE = 1/2 mv², where m represents mass, and v is the velocity of the object. Kinetic energy is dependent on both the mass of the object and the square of its velocity, meaning that even small increases in speed can lead to significant increases in energy. This energy is observable in moving objects, such as cars, flowing water, or flying airplanes, and plays a key role in various physical phenomena.
