It's simple physics... momentum.
Conservation of momentum:
mass1 * velocity1 = mass2 * velocity2
When you depress the clutch you disconnect some of that mass from the system, therefore the velocity of the system instantaneously increases.
If you disconnect some of the mass then the momentum should DECREASE. Your theory is not valid in this case. Also u cannot create more momentum without some outside force acting upon the mass.
