what is kinetic energy?Also say its unit.

Answer» <p>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. Kinetic energy is usually measured in units of Joules (J); one Joule is equal to 1 kg m2/ s2.</p>
