- 8. Ch.9, Lesson 1 Motion and Speed • How can we measure motion? • Vocabulary: Position Distance Motion speed 8 - Motion can be fast or slow. Distance -It is how far an object is from one position to another. Measuring the length between starting position and ending position give you the distance. - Measured by: Ruler & Measuring tape - Units: Cm, meters & kilometers.
