v1 is design speed and v2 rotation speed
v1 = initial velocity v2 = final velocity
V1 is a v-speed, in aircraft terminology v-speeds are specific speeds for various operations. Takeoff speed is V2, maximum speed with landing gear extended is VLE, maximum speed with flaps extended is VFE. These speeds vary from model to model & so its important for pilots to familiarize themselves with the v-speeds of any aircraft they intend to fly. V1 is the maximum speed during takeoff at which a pilot can safely stop the aircraft without leaving the runway. This is also the minimum speed that allows the pilot to safely continue (to V2 takeoff) even if a critical engine failure occurs (between V1 and V2). So basically V1 is the point of no return, once you've hit V1, you are committed to the takeoff, even if you lose an engine you're better off flying than you are trying to stop.
( | V1 - V2 | / ((V1 + V2)/2) ) * 100
[ ((v2 - v1) / |v1|) * 100 ]
To find the initial speed of spaceship one, we need to apply the principle of conservation of momentum. Since the two spaceships have equal masses, their momenta will be equal and opposite. The momentum of spaceship two is given by 150 kg * V2, where V2 is the initial speed of spaceship two. The momentum of spaceship one is given by 150 kg * V1, where V1 is the initial speed of spaceship one. Since they have equal magnitudes, we have 150 kg * V1 = 900 kg * (-V2). Solving for V1 gives V1 = - 6 V2. Since we want the initial speed in magnitude, the initial speed of spaceship one is 6 times the initial speed of spaceship two in magnitude.

The most common multi output systems are used for getting differential output. i.e., if V1 and V2 are the 2 outputs, then usually the difference, V2-V1 or V1-V2 is used.

The equations of motion that relate velocity, distance, time and acceleration for the specific case of "constant acceleration" can be written as follow, acceleration a = (v2 - v1)/t from which v2 = v1 + at The distance covered during t time d = vav x t, where vav refers to average velocity in the process from v1 to v2. For the case of constant acceleration vav = (v1 + v2)/2. Substituting in d we get d = (v1 + v2)/2 x t from which, v2 = 2d/t - v1 If we take the constant acceleration to be zero, a = 0, you can see that the second equation we wrote becomes, v2 = v1 (There is no acceleration), so our equation for the distance d becomes, d = v1 x t = v2 x t
Two vectors; V1 + V2=0 where V1= -V2, two opposite vectors.
V1 is the critical decision speed during takeoff, representing the maximum speed at which a pilot can abort the takeoff safely. Once the aircraft reaches V1, the pilot must continue the takeoff even if there is an emergency, as stopping would likely exceed the available runway length. "Rotate" refers to the moment when the pilot pulls back on the control yoke or stick to lift the aircraft's nose off the ground, initiating the climb phase of the flight. This action typically occurs at a speed called V2, which ensures a safe climb even in case of engine failure.
the V2 rocket was bigger and faster than the V1 flying bomb. the V1 being a flying bomb was smaller and had a pulse jet engine and the V2 which was a rocket had a bigger rocket engine. ACTUAL SIZE COMPARISON: V1: Length: 25' 4" wingspan: 8.32 meters V2: length 14 m (45 ft 11 in)
