• 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.

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.

• 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)

Relative Motion
