Question

what's the kinetic energy of an object will be affected if the velocity is increased 3 times​

Answer 1

Answer: The kinetic energy of the object increases by 9 times

Explanation:

We know

KE = mv²/2

If velocity is increased 3 times

m(3v)²/2 = 3²mv²/2 = 9×mv²/2 = 9×KE

We see that the kinetic energy increases 9 times
