Velocity has direction

“Velocity is often confused with speed, but the two concepts are very different. Speed is just movement; even if you are running in place, you have speed. Velocity has direction. You must go somewhere in order to have velocity. This model teaches us that it’s much more important to pay attention to where you are going and not how fast you are moving. No one wants to be a hamster in a wheel, focused on moving so fast that we lose track of what we’re trying to achieve. While speed ensures movement, velocity produces a result.”
