Detailed explanation-1: -Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

Detailed explanation-2: -To calculate kinetic energy, we use the formula kinetic energy = 1/2 mass x velocity^2. Kinetic energy is the energy of motion, so any moving objects have kinetic energy okay so kinetic energy the formula we use for kinetic energy is one half times the mass of the object time the velocity of the object squared.

Detailed explanation-3: -The fundamental reason why there is a half in the kinetic energy formula actually comes from special relativity from a “more complete” version of the kinetic energy formula. The brief explanation is that this kinetic energy formula of ½mv2 can be considered as an approximation of special relativity.
