Year 10 Force and Motion Practice Test

Time is the measure of how long motion lasts. It tells you the duration from the start to the finish of a movement. Distance describes how far something travels, not how long it takes. Speed is how fast something moves—distance divided by time—so it’s about rate, not the length of time itself. Velocity is speed with a direction, still focusing on rate rather than total time. In practice, you’d use a stopwatch to capture the duration, for example, how many seconds it takes to run 100 meters.
