Friday's class

On Friday, we started class by taking notes, and trying to write formulas for constant velocity and acceleration graphs. This was a good exercise that showed us that we do not know as much as we think we know. After that, we took notes involving the formula for constant acceleration and a more in depth analysis of newton's 2nd law. After the 1st half of class ended, we then started thinking more about the relation of mass to motion by doing a lab that showed us that the more mass there is, the less velocity there is .(I was not in the room for the explanation, so do not quote me on this) We did this by using a flimsey piece of metal and measuring its velocity w/ a motion detector. We learned that when we added mass, the velocity was lower than w/o extra mass.
