Question

When velocity of an object is increased 5 times, what is the change in its kinetic energy

Answer 1

ke=1/2mvsq.
if v=5v
then
ke= 1/2m(5v) Sq.
and 1/2m is constant
therefore ke increases by (5v) Sq.
that is 25 times

Answer 2

Answer:

The change of kinetic energy would increase by 25 times when the velocity of the object is increased 5 times.

Explanation:

The directional speed of an object in motion as an indication of its rate of change in position as observed from a specific frame of reference and measured by a specific time standard is known as velocity.

Let the body's velocity be ′ v′′.

Whenever the velocity is increased five times, the velocity is 5 v.

Kinetic energy is known as EK.

K.E = $\frac{1}{2} mv^{2}$

New Velocity=5v

New K.E= $\frac{1}{2} m(5v)^{2}$

=25( $\frac{1}{2} mv^{2}$)

=25$\times$K.E

Therefore, When the velocity is increased by 5 times, the kinetic energy increases by 25 times.
