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.
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.
Can vectors be added to each other?
Yes, two vectors of similar kind can be added. For example we can add a distance vector with another distance vector. But we cannot add distance vector and velocity vector.
Two things vector have?
Length and direction.
Distance between speed and velocity?
Usually, speed just tells you how fast something is moving on average (total distance traveled divided by length of time), but the velocity also includes which direction it is traveling (usually by including the two or three dimensional position it was in when you start the measurement and end it) so we call it a vector.
