Back to Work

Weekends are always too short and Mondays are always too long. At least most of you were engaged in lab activities. Honors Physics - make ready for tomorrow's exam! Its long block, so you should have plenty of time, but be ready to use that time efficiently. I added more non-multiple choice problems this go around. Gives you a bit more opportunity for partial credit. Regardless, momentum starts right on the heels of the exam.Physics began, and some completed, the elastic potential energy lab. Tomorrow we will finish the lab discuss the whole lab unit from the perspective on conservation of mechanical energy. Physical Science investigated momentum. Technically, you were examining collisions and how they demonstrate conservation of momentum, but we'll bring that piece into the picture after we have basic momentum a bit tighter under the belts. But, it was fairly clear that if you give an object with a fixed mass more velocity, you give it more momentum. The target moved further with the increasing momentum of the cart. Later, I'll show you how to use a bit of math to model the situation But, in the meantime, here's a good video that touches on momentum, impulse and conservation of momentum (and Spiderman, which is always acceptable).
