5 m v 2. Where KE is kinetic energy in joules m is mass in kilograms and v is velocity in meters per second. For example if a an object with a mass of 10 kg m 10 kg is moving at a velocity of 5 meters per second v 5 ms the kinetic energy is equal to 125 Joules or 12 10 kg 5 ms 2.
½ m v².
Where mass of the body m the velocity with which the body is travelling is v. 12 mv 2 where m stands for mass and v stands for velocity. Translational kinetic energy of a body is equal to one-half the product of its mass m and the square of its velocity v or 12mv2. Where mass of the body m the velocity with which the body is travelling is v.
