Last weekend I went to Ice Palace in search of Physics and once again it POPPED out to me! I realized that when I pushed off the wall, my reaction(skating back) was equal and opposite of my action (the push) as described in one of my earlier journal’s on Newton’s Laws. This however, meant that the force I exerted on the wall was just about equal to the force at which I was skating backwards (subtracting friction). This meant that my old physics knowledge was useful and I could determine my acceleration back using the theory of conservation of momentum, impulse, and Newton’s Laws. I could do all these things using logger pro but, because I was a little too lazy for that thought I would simply explain the topic. My prior Physics knowlede all came together and helped me understand the hard yet, fun task of ice skating.
