So today we took a reassessment during class and got a sheet that had our overall reassessment grades. We talked about simple harmonic motion and watched a movie about it, where we saw the x and y components, but I never fully understood it. Simple harmonic motion has to do with spinning objects and squiggle graphs because that is what we saw in the movie. This is the type of motion that we saw::

We also talked about the graphs that were for homework. C2 vs. C1 fully confused the class and I will try my best to explain the little bit that I understood. C2 is the constant/slope for the Air resistance vs. Terminal Velocity Squared graph and C1 is the constant/slope for the normal Air resistance vs. Terminal Velocity graph. So basically C2 is Fair/Vterm^2 and C1 is Fair/Vterm. C2 is a lot bigger than C1 when normal sized objects are involved, but with microscopic objects C1 is a lot bigger. That was monday.... and i dont really know who hasnt scribed but i dont think eliza has so... ELIZA!! :)
