Yesterday in class we finished notes on motion and discussed some relative motion problems, along with distance and displacement related ideas.
Today we had our Motion Map and Graphing Activity #2; the wheel and axle. These started really slow and gradually increased in speed as they went down a ramp. Everyone had hands on the data collection which was fun, then we tried a couple of different ways to graph (even with tape and no numbers!)
Finally we shared different types of graphs and discussed axis labels... some groups made graphs of position or distance / time and some groups unknowingly graphed speed or velocity versus time.
We wrapped up by discussing what the slope of a velocity / time graph would indicate... units we came up with in most classes were centimeters per second per second. This is how much faster (in centimeters per second) the wheels got each second.... AKA acceleration!
HMWK (due Tuesday) Read p. 76-80, p. 80#1-7
