What is the result if you subtract a velocity vector to another velocity vector?
The result will also be a velocity vector. Draw the first vector. From its tip draw the negative of the second vector ( ie a vector with the same magnitude but opposite direction). The the resultant would be the vector with the same starting point as the first vector and the same endpoint as the second. If the two vectors are equal but opposite, you end up with the null velocity vector.
How is velocity diffrent from speed?
Velocity is a vector, and so it has two components -- magnitude (speed) and direction. Speed is a scalar, and it is the magnitude of velocity, a vector.
How does vector calculus apply in fluid mechanics?
The velocity at each point in the fluid is a vector. If the fluid is compressible, the divergence of the velocity vector is nonzero in general. In a vortex the curl is nonzero.
What does the velocity include that the speed does not?
Direction. Velocity is a vector, speed is a scalar.
Is 55 miles per hour a vector?
No. It is a speed (a scalar) but not a velocity (a vector).
