Speed
... Motion: When an object changes position over time when compared with a reference point. You can describe the direction of its motion with a reference direction. Direction: N, S, E, W, up and down. Point of Reference: buildings, mountains, etc. Speed: Speed (s) depends on distance (d) and time (t). ...
