Monday, November 24

It's a slow moving crowd today, wishing that the holiday would come sooner. But we are promised an easy day tomorrow, seeing as our brains will be nothing but mashed potatoes. But we must get down to business. We pick up: Unit 5A objectives, Unit 5A Reading Guide, and a Collisions demo. The next unit begins! Amongst the new papers, we are also graced with our Unit 4 tests, and our Unit 4 reading guide, great. We go over the test answers, but I can't go over that here. Shush.

Sometime after Thanksgiving we will be done with Unit 5A and for part B we need to go out and buy a __protractor and a ruler__. The ruler must have **centimeters**.

Next, according to the board we will be talking about Demos. The picture below shows two vehicles colliding, like in the demo. Which car got the most force in the collision? They both got the same! This answer shocked and amazed the class with each trial ending with the collision force being equal regardless of velocity, mass or friction. Tomorrow we will do part B of the collision lab!
