The kinetic energy is the energy possessed by an object due to its motion. The amount of kinetic energy (KE) possessed by an object depends upon its mass (m) and its speed (v). The formula for calculating the kinetic energy is
KE = 0.5 • m • v2.

The formula for kinetic energy is stated in the Formula Frenzy section above. The amount of kinetic energy possessed by an object depends directly upon the square of speed (or velocity). An increase in speed will increase the kinetic energy. In fact, an increase in the speed by a factor of 2 will increase the kinetic energy by a factor of 22 or 4.
