Describe what is happening in terms on one of Newton's Laws of Motion. f o l d 16. 17. Hot Air Balloons:  The balloons are released and drift up in the air. Describe what is happening in terms of one of Newton's laws of motion. f o l d 17. 18. Roller Coaster Corners: If you are not strapped into the car, you will be flung out of the coaster car when it hits the turn. Why? f o l d 18. 19. Newton's Cradle:  If you pull out the steel ball on the left, what will happen when it swings back to the waiting 5 balls? f o l d 19. 20. Tossing a coin in a moving airplane:  The plane is cruising at 500 miles/hr. You toss a coin up in the air. Where does it land and why? f o l d 20. 21. Seat Belts:  Use the concept of INERTIA to explain why you are required by law to wear a seat belt in an automobile. f o l d 21. 22. Washing Machine:  When the water is drained out and the spin cycle starts, why does the spinning drum cause the clothes to become less wet? f o l d 22. 23.
