You Should Just Fess Up

No one has come forward to claim responsibility for my illness and that's just chicken-baby behavior, if you ask me. So, I get to suffer without retribution against the perpetrator, which would make me feel much better...

Physics A reviewed the concepts of weight and the normal force and got extra practice calculating the normal force for a variety of situations. We'll get back to specific forces on Friday, but tomorrow is set aside for a lab that lets folks examine the tenets of Newton's 2^nd law of motion. Physics B conducted that lab today and found that, barring the normal noise in the data, there was a direct relationship between the applied force and the cart's acceleration and an inverse relationship between the cart's inertia and the acceleration (when the applied force was held constant). We'll address any problems or questions for the lab tomorrow, before turning attention to friction.

Introductory Physics reviewed their work with weight and free-fall before getting some focused practice on the kinematics of free free fall. We'll go over those problems tomorrow in class, before adding a layer of complexity to our discussions by looking at orbital or projectile motion.

Honors Physics got a quick review of mechanical energy and were allowed class time to work on problems/questions dealing with kinetic energy, gravitational potential energy, elastic potential energy and the work-energy relationships. Tomorrow, we'll take a look at conservation of energy - a powerful tool for problem solving when the acceleration of an an object cannot be assumed to be constant.
