or (from school) X:\\Physics\physics\circularphysics.htm

 

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

wavesims/shm/shm.html

 

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

circularMotion/circular3D_e.html

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!
