Lesson 74: Measuring Speed

Vocabulary distance The length measured between two points error Unavoidable variations between a measurement and the true value of a quantity that occur when measurements cannot be made with greater accuracy. rate A ratio of two different kinds of measurement. Speed, the ratio of distance to time, is an example. speed The rate at which an object moves, equal to the distance traveled per time interval. time interval The time between two events. velocity The velocity of an object includes both its speed and its direction.

Why do you think speeding is a factor in about 20% of fatal car accidents?
