Handed back Rocket Lab 1, RA 2.5, Abstract Reasoning Extra Credit Worksheet, Reaction Time Lab
Asked if students made money from showing Reaction Time Lab to parents.
Went over Sunken Track, Straight Track problem. Demonstrated analogy with running around a track. The one with the higher average speed wins even though they have the same final speed.
Went over acceleration down slope problem. Sketched v vs t curves and showed that for the same area (same displacement) it takes less time for the curve with a greater initial slope.
Handed out practice problem worksheet and let students work on it. Showed demo of problem 3 using track and fan glider.
Test on Thursday.
