The only difference between velocity and speed is that velocity has a direction, and so is a vector quantity. Average velocity = \(\frac{\text{displacement}}{\text{time}}\) Displacement is the ...

Displacement is a distance and a direction, eg \(170m\) south. Velocity is a speed and a direction, eg \(12 m\,s^{-1}\) on bearing 055 (55º East of North). The term acceleration can refer to a ...

It is a vector quantity, meaning it has both a magnitude and a direction. Angular velocity (ω) is defined as the rate of change of angular displacement with respect to time. It describes how fast ...

So, to really measure the air velocity at ... direction and -2 in the y direction, you could write that as: If you wanted, you could find the magnitude of this vector displacement with a value ...
