WebVelocity describes the speed and direction of an object. As with speed, it is useful to describe either the average velocity over a time period or the velocity at a specific moment. Average velocity is displacement divided by the time over which the displacement occurs. v avg = displacement time = Δ d Δ t = d f − d 0 t f − t 0 Web20 de dez. de 2024 · The basketball constantly changes velocity as it rises and falls. Describing changes in velocity, and how fast they occur, is a part of describing motion. What Is Acceleration?. How are changes in velocity described? The rate at which velocity changes is called acceleration.
