I Didn't Want to Come Back To This

Nice, fun, long weekend and we come back to cold, rainy misery. Not really worth getting out of bed, was it?

Regardless, it was a busy day all around. Physics A and B reviewed their work on conservation of momentum and then looked at the concept of power. Remember that power is a rate function: the rate at which work is done, the rate at which energy is transformed, the rate at which energy us used, etc. A machine with a higher power rating than another doesn't do more work than the latter, it only does the work faster. The practice problems took us a bit longer than expected, so we pushed tomorrow's test back to Thursday and will use all of tomorrow for review. On Friday, we begin our unit on momentum, with A Block discussing the nature of momentum and impulse and B Block working on a lab targeting the impulse-momentum theorem.

Introductory Physics completed their impulse-momentum theorem labs, which are due on Monday so you have plenty of time to get help with the calculations or the writing before you hand it in for credit. Tomorrow, we'll go over the momentum quiz and begin working on items from previous MCAS exams centering on forces and momentum. We'll go over these on Thursday and have a general chapter review before having our exam on Friday.

Honors Physics enjoyed their Chapter 6 (Momentum and Collisions) exam and will start with circular motion and gravity tomorrow. It will be a change of gears, but will broaden our model of motion quite nicely.
