INVESTIGATIONS INTO CIRCULAR MOTION!

0) Finish anything interesting from last time Especially ripple tank and circular motion

Wave observations: waveobserve.htm simulations found wavesims.htm

to investigate the phenomena of waves waveinteractions.htm

Remind yourself of the relationship between circles and waves with

Vary length and mass to see the effects on circular motion with

1)WEB QUEST:

Take notes (IN WORD OR ON YOUR OWN PAPER!)

on each site to make sure you understand the concepts of:

Circular motion = wave= periodic motion 1WL=λ=2πr

Angular vs. linear velocity

Angular vs. linear acceleration

Centripetal acceleration = v2/r and centripetal force (towards the center)

2)INTERACTIVE PHYSICS: (only at school).. use to demonstrate each (see page in X:\Physics\physics\CircMotionFiles\index.htm or http://www.richtherrn.net/physics/CircMotionFiles/index.htm

3) Begin reading Chap 10 (Circular Motion) for notes Fri/Monday. Tue prepare for LakeC!
