Both the mass and velocity make a difference but if you were to double the mass, the kinetic energy would also double.
Double the velocity and energy goes up squared.
m = 5
v = 5
E = 0.5 * 5 * 5^2 = 62.5 Joules
m = 6
v = 5
E = 0.5 * 6 * 5^2 = 75 joules
m = 5
v = 6
E = 0.5 * 5 * 6^2 = 90 joules
increases in mass = linear increase in energy.
increases in velocity ≠ linear increase in energy.
