Today, although mostly review, was actually pretty stressful/hard. This was because our lab, the air track lab, did not work out well. However, we soon decided to do one lab as a class which made things much clearer and easier to understand. Also, when everything was explained, it really helped and solving for acceleration and such became much simpler. Today, we went into more depth/reviewed "F=ma" or more complicated versions such as W-T=ma. Although this is basically the same formula (very similar) to "F=ma", it was very hard for me to understand clearly at first. After lots of practice on the board I began to understand and soon were easily solving problems with pulleys and things that were hard for me at first! I hope I continue to be able to grasp these concepts and am definitely up for more practice in our "fatteh packets"....
PS I sure wish I had a tree house pulley like these kids!
