Kinetic energy = 1/2 mv2
Rate of change of kinetic energy keeping mass constant
KE = kv
Its a linear relation
On the other hand, if we keep velocity constant and increase mass
KE = k
It will remain constant
Hence, change in velocity will cause a greater change in Kinetic energy

Kinetic energy is directly proportional mass as well as velocity. But, you must note the fact that kinetic energy is directly proportional to the square of velocity. Therefore, changing the velocity will cause a greater change in kinetic energy.
