Today we began to discuss FORCE! Technically this is dynamics...the study of WHY things move. We used the Forces Cheat Sheet (on Documents Tab) and listed several common forces that we will discuss throughout the class.
Then we played with the Kick Dis Power Puck:
We came to the conclusion that this toy was a pretty good model for something moving without friction. We also noticed that it exhibited Constant Velocity when it was turned on and moving without anyone touching it. To further explore this idea we drew system diagrams and Free Body Diagrams. A fabulous discussion followed about forces being balanced...Good Stuff!
