This weekend I watched a lot of football. Watching it this week made me realize how bad it must hurt to get hit by a 240+ pound linebacker. The average running back runs about 4.72 m/sec and has a mass of about 97.5 kg. If the linebacker stops the running back in 1 second, the force on the running back is about 460 newtons. Due to newtons third law, that same force is thrown onto the linebacker as well. A linebacker that is famous for his powerful tackles is James Harrison for the Pittsburgh Ste
During this week in AP Physics C, we have begun our studies in Dynamics. At first it was not too bad... then came air resistance. It seems like a pretty simple concept but it is in fact not. I don't have much experience in Calculus yet, so the differential equations are still pretty difficult to understand. There is still a good amount of time before the test for me to study this concept so hopefully I will get a good grasp on it before the test. Other than the differential equations, the confus
