velocity of a body is increased by 5 times what happens to its kinetic energy? Share with your friends Share 1 Lokesh answered this Formula for kinetic energy is 1/2 m v^2 If velocity of a body is increased by 5 times, then v^2 will increase by 25 times but mass is still of body as it is not changing. So, kinetic energy will increase by 25 times. 11 View Full Answer Shivani Prasad answered this KE = 1/2 mv^{2}If the velocity is increased by 5 times then (5v)^{2 }= 25v^{2}Therefore the velocity is increased by 25 times. -1
