Detailed Solution

Change in velocity will cause a greater change in the kinetic energy of a body.
The energy from the movement of a body is called Kinetic energy.

K . E . = \frac{1}{2} m v^{2}

, where

m

is the mass of the body and

v

is the velocity of the body.
Kinetic energy is directly proportional to the mass's product and the velocity square. So, by changing the velocity, a greater change in the kinetic energy of a body is caused. Because of this, a change in velocity affects kinetic energy more than a change in body mass.
