V1 speed is the speed beyond which the takeoff should no longer be aborted. Above V1, the takeoff must be continued unless there is reason to believe that the aircraft will not fly.

VR (Rotation) is the speed at which the pilot begins to apply control inputs to cause the aircraft nose to pitch up, after which it will leave the ground.

V2 is takeoff safety speed. The speed at which the aircraft may safely climb with one engine inoperative.
