Three V speeds which pilots must use on take off

Every time when pilots need to take off, they will need to comply with the following three V speeds:

V1 - also known as decision speed (the point of no return) is the maximum speed at which pilots can reject the take off, in the event of an emergency situation. Another important fact for V1 speed is that once the speed is reached, pilots must continue and they will must take off no matter the emergency.

Vr - this is the speed when the non-flying pilot says "rotate", and the pilot flying pulls back the control - yoke for Boeing, side stick for Airbus) in order to raise the nose and the aircraft lifts off the ground, and start to climb attitude. This Vr (rotation speed) assures that a lift-off is possible even in case of an engine failure.

V2 - this is the minimum required speed that needs to be maintained up to acceleration altitude, in case of a bird strike or engine failure. In other words, if V2 speed is reached the aircraft can climb safely to the minimum altitude in order to perform a 'Go around' and return back to airport in case of emergency after V1 speed.
