Honors Labs

The accleration lab reports were mostly pretty good. However, there is still some sloppiness in wording. Many of you said that the velocity increases as the distance. While it is true that the velocity does increase when the distance increases, the phrase increases as means proportional to. i.e. if a increases as b then a = constant x b. Therefore it is v squared that increases as distance not v. This is crucial to the meaning of the lab which is meant to confirm one of our kinematice equations but more importantly, to lead you to the concept that force exerted over a distance changes energy.
