Consider the formula for determining kinetic energy:

K.E.= 1/2 m V^2

Which factor would have the greatest impact on the magnitude of kinetic energy?

a
mass
b
velocity
c
gravity
d
Impossible to determine

b. Velocity

The factor that has the greatest impact on the magnitude of kinetic energy is the velocity (factor b). In the formula for kinetic energy, the velocity is squared. This means that any changes in velocity will have a greater effect on the magnitude of kinetic energy than changes in mass (factor a) or changes in gravity (factor c). Therefore, velocity has the greatest impact on the magnitude of kinetic energy.
