9. The illustration below shows a ball at several positions during its bounce. If you were to watch it thrown you would see that the ball is in motion.

10. Motion- pg 9. in book Motion is the change in position over time. (glossary word) As the ball bounces both its horizontal and vertical positions change. (glossary word) If you missed the bounce you would still know that motion happened. How? Because a change of position occurred. That is evidence of motion.

11. A change in position tells you that motion took place, but it does not tell you how quickly the object changed position. Speed is a measure of how quickly or slowly an object changes position. (glossary word)

12. Relative Motion If you sit still in your chair, you are not moving. Or are you? You do not notice your position changing relative to everything else in the room. But if we could observe you from space, we could see that you are constantly changing positions with the Earth as it travels around the Sun.

13. Consider your car or bus ride to school… An observer in the car would say that the stop sign changed positions and the car did not. An observer by the sign would say that the car changed positions and the sign did not.
