Weight Dependence of Friction
( I don't like the surface area friction demo. So, last year, to show the dependence on surface area, we ended up only using the two different sized blue wooden planks dragged on smooth surface of particle board with 4 x 1kg masses spread evenly on each, spring scale reads about 13 Newtons each: 15"x10.5" = 503g and 7.5"x5.25" = 130g + 381g mass)

For Thursday's class in 203 (9:30 am), can I also get two bouncing balls? One much larger than the other. For example a kickball and a superball, or better a basketball and a tennis ball.
