Still on Forces

Regardless of the specific concept we've attacked so far, forces have been lurking in the background. Welcome to the wonderful world of matter. Physics, today, discussed momentum and impulse, which branch from and look back towards our discussions of Newton's laws of motion. Tomorrow, we begin looking at conservation of momentum, which is a consequence of, specifically, Newton's third law of motion. Physical Science examined buoyant forces in lab. A couple of groups had slightly quriky results, but other groups work nicely demonstrated that the apparent lost of weight of an object (the buoyant force) was equal to the weight of the displaced water. The homework questions should be approached in terms of the forces involved. We'll add the ideas of floating, sinking and density to the mix tomorrow. Honors Physics prepared for tomorrow's exam. Even though I make light of it, do make sure that as we move into the next chapters that you remember to do your work with your calculators in radian mode. Every year, people get very frustrated that they aren't getting their homework problems right and it turns out they are working things in degrees.
