Class on Wednesday

In class Wednesday we went over a lot of new material with forces. One of the main concepts was that in the absence of forces an object moves with a constant velocity, that was one of the things we were all supposed to understand after that class period. We started off going over that the general wasy to describe forces is that forces require something to exert the force on and something that exerts the force. From now on, we will be describing a force as, The force of something on something. We also learned how to describe such a generic term such as gravity, the non-contact gravitational force of the earth on the block. Then we went over a system schema, how to draw them and what forces and objects they should include. The free body diagram was another diagram that we learned how to incorporate with forces, and the slope of the rays from the dot if the surface is sloped. Also instead of writing out the non-contact gravitational force of the earth on the block every single time we learned that you can do this, Fg, E-->B and that is telling the exact same thing. The class on wednesday covered a lot of material, and all of it was very interesting. The next scribe is... Joe for the class on Friday which we already had.
