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 scalar acceleration or an acceleration vector. So far ...

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 ...

A streamline is a line that is tangential to the instantaneous velocity direction (velocity is a vector, and it has a magnitude and a direction). To visualize this in a flow, we could imagine the ...

When [Michael Rechtin] learned about Radial Vector Reducers, the underlying research math made his head spin, albeit very slowly. Realizing that it’s essentially a cycloidal drive meshed with a ...
