V1 vs vmcg

Hello
First thanks for your replies.
To set things straight, as far as v1 is concerned as weight increases the aircraft carries a greater inertia and in a balanced field condition results in a greater stopping distance thus v1 must be reduced to bring the airplane to a complete stop. On the other hand, the heavier the airplane the greater is the thrust required to accelerate, the stronger is the yaw resulting from an engine failure and thus the greater is the rudder authority needed to counteract the yawing moment.
In the challenger 605 these two speeds meet at 111 knots, representing the minimum v1 speed.
