BSL Physics Glossary - time interval - definition

A longer length of time can be divided into a number of shorter periods of time, all of the same length. These are called time intervals. For example, say you wanted to measure the speed of a car over a journey taking an hour. You could divide the hour up into time intervals of ten minutes. You record the speed at each ten-minute interval. You may find that the car is travelling at a constant speed, or maybe it is slowing down and speeding up over its journey. That's how you can use time intervals.
