If you can't reach V2, how do you achieve flight?

In a multi-engined a/c, the V1 is highest speed above which the plane can be
stopped on the runway, it is also the speed at which (even if there is a
critical engine failure) you can still safely achieve V2 IF you have engine
power from the other engines.

However, in a single engined aircraft, the latter part of that is rather
optimistic- if the engine goes you will not keep on accelerating. In a
multi, the remaining engine(s) should allow you to reach V2. However, if you
don't, won't be flying.

Vr is the speed at which the nose wheel can be lifted.

I expect you, and others, have been Googling. Trying looking at the official
definitions of the V speeds and then thinking about the physics.
