• Hi Al, I may come in around 3:00 to look around to see how I could use the air track carts connected to a small spring scale and show how doubling the mass requires you to double the force to get the same acceleration. They discuss this at lengths in the textbook so I would like to see if it is easilly observable. Thanks.

• bathroom scale only to stand on spring scale and carts with weights to match spring scale. Basically I want to show if I double the weight I must double the fore to get the same speed. Two green grocery scales for students to use to push against each other

• 1) One bowling ball to be used as a prop. 2) Heavy block pulled by a spring scale to demonstrate work (weight of block and scale sensitivity should match up )

• 1) Two hover disk riding on air with and without velcro 2) Basket ball with small ball on top to show large velocity change of small ball in collision 3) Virginia map to show cm.
