Weak Monday

With the field trip today and a slew of general absences, classes were a little light on attendance. No matter, we'll catch people up tomorrow.

Honors Physics took their work and energy exam today and will leap into momentum on Wednesday with a lab on the impulse-momentum theorem. Interested people can read ahead in Chapter 6, but the lab does a good job on its own introducing the concept and letting you work with the math behind the idea.

Physics B, with a rocking total of 3 people, conducted two lab investigations, both of which targeted energy and its conservation. One lab looked at gravitational potential and kinetic energies and the second targeted kinetic and elastic potential energies. The lab nicely showed that regardless of how energy was divided up between the players, the total value remained constant. We'll go over the lab on Wednesday and take time to discuss kinetic and elastic potential energy in more depth.

Physics F discussed kinetic energy and elastic potential energy in class and got some practice with the problem solving for the various energy types and conservation of energy. We'll go over conservation of energy and review these problems in class tomorrow.

Physical Science went over their forces math quiz and were introduced to the concept of and formula for momentum. Remember not to confuse momentum with inertia - all mass has inertia, but only mass in motion has momentum. We'll go over the homework problems in class tomorrow before digger deeper into momentum and its conservation. The solutions to the homework problems can be found here.
