7Px 16 Pipiri 20157Px 16 Pipiri 2015What we will do What we will learnExamine energy changes in SHM, generally and particularly (in a perfect world)
What the pattern is.
Extend the above to a real situation
How to handle energy losses because of friction, heat
See what happens to SHM when it is forced
Where the bell curve for “response” comes fromWhat resonance is
A look ahead to the rest of this week.Today: Energy, damping and resonanceTomorrow: Review of Mechanics+HRTFri: Formative Assessment for both classes
How to stay on track for the 20th of November
