Tuesday, Feb 17, 2009 - Block 3 IB Physics 2

Lectured on SHM
Talked about radian measurements, angular frequency, and related linear velocity to angular velocity.

Showed demo with turntable and related SHM to Uniform Circular Motion.

Derived the equations of motion for SHM from the projections of Uniform Circular Motion.

If Newton's 2nd Law can be written in the form: a = - C * x, then you can Zap (2) it to get w^2 = C, and find the frequency, period, and equations of motion.

Did several examples using combinations of springs. Started example of block bobbing in the water.

Handed out worksheet on SHM problems and asked students do to 1,2,3,4, and 6 for homework.
