Does Anyone Like Getting Up When Its Dark?

I think there should be a law that no one has to get up or go to work if it is still dark outside. I'm not sure how third-shifters would be able to stay employed, but I'm sure someone would think of something...

Honors Physics battled their forces and laws of motion exam today and some will continue the battle tomorrow morning. I haven’t even looked at the papers yet, so I can’t give you a head’s up on the performance rating, but people were definitely looking like they were giving it their best go. Tomorrow, we’ll start discussing work and kinetic energy. The lab on Friday will concentrate on the conservation of energy in simple harmonic motion, so the reading you’ll do tomorrow night should prep you for that investigation.

Physical Science B started their exam review and spent some time working review problems for universal gravitation. As promised, I found worksheets dealing with GRAVITY and MOMENTUM that you can work on for extra practice. Tomorrow, we’ll do the momentum lab without extensions so that we can have a little time at the end for more review. Physical Science E completed their discussion of conservation of momentum and began the review process for Friday’s exam. You can also access the extra GRAVITY and MOMENTUM worksheets and bring questions with you to class tomorrow. For both blocks, #6 of the momentum worksheet can be skipped. You have to use some of the kinematics formulas that we didn't go over in class, but you can give it a whirl with your MCAS formulas sheet, if you like!

Physics F and G began their exploration of work today and found that it is not exactly what they might have thought. Many people equate force and work; however, you can apply a gigantic force and still do not do work if the object doesn’t move. Plus, don’t forget that the force used to calculate work might only be a component of the total applied force. Vectors rear their ugly head again in that you can only use the component of force in the plane of the object’s motion to assess work. Tomorrow, we start in on kinetic energy and its relationship to work.
