What is V1, V2 and VR?

Hi IFC,
What is V1, V2 or VR?

I may be wrong but I think they are referring to speeds. If they are, I’m not requesting the specific speeds but I’d like to know what they represent. If that makes sense

Thank you for help :)

V1 is the speed by which time the decision to continue flight if an engine fails has been made. It can be said that V1 is the “commit to fly” speed. V2 is the speed at which the airplane will climb in the event of an engine failure. It is known as the takeoff safety speed. And VR is the speed that you rotate at.
