HMWK due Monday: Read p. 135-140. P. 143#1-6
Yesterday we worked a GPE-KE - work marble lab where energy was calculated for a marble atop a ramp, then we rolled the marble down and allowed it to push a folded card until it came to rest. We altered the energy input based on the marble's height and the number of marbles, and recorded the change in stopping distance. It turns out that since Work (Force * distance) has the same units of energy, when the energy was doubled or tripled, the stopping distance was doubled or tripled as well - demonstrating that the Joule is a proportional unit for Work and Energy.
Today we had notes on Work and forms of energy / the fate of all E --> Thermal Energy.
Monday's class will be consumed by looking into Thermodynamics principles, and we'll discuss homework. Later Monday and Tuesday will involve application /connection of the idea/equation of work to Simple Machines.
