Today was our last Physics class of 2011. We further discussed the relationship between Actual Mechanical Advantage (AMA) and Ideal Mechanical Advantage (IMA). I learned that no system will ever have 100% efficiency due to real world losses, such as friction. We also went over our homework. One problem I found interesting was the one about the pyramids. It was interesting to see how physics helped people thousands of years to build amazing structures, even with their limited technology. I think we don't take into account how much physics impacts our lives.
