In physics, the motion of objects is described by their velocity, speed and the way that velocity itself changes over time. Central to this description is the concept of acceleration—the rate at which velocity changes. Yet the term magnitude of acceleration focuses on the size of that change, irrespective of the direction. This article unpacks…
