Question

7. The kinetic energy of an object is K. If its velocity is doubled than its kinetic energy
will be ​

Answer 1

Answer:

if the kinetic energy of an object is K . if you will doubled than the kinetic energy will be double

Explanation:

Answer 2

Answer:

Explanation:

Here,

Kinetic energy= K

Since we know the formula for kinetic energy is ½mv² which is = k

Now when the velocity is doubled;

Therefore

Kinetic energy

= ½m[2v]²

=½m4v²

=4×½mv²

=4×K

Hence kinetic energy increases by four times.
