KE 05 x mv2500 J. KE ½ 1500 kg 28 ms 2. The kinetic energy formula is expressed as.
Therefore by the above formula we can say that kinetic energy is directly proportional to the mass and square of the speed of the object in motion.
For example doubling the velocity quadruples its energy. The kinetic energy formula is expressed as. That is a big increase in energy. Kineticenergy frac 1 2times mass times speed2 E_ k frac 1.
