The impact of physics affect my personal performance in many ways throughout marching band. First off, I will start out with explaining physics and the laws of it. Newton’s laws of motion are, one, “When viewed in an inertial reference frame, an object either is at rest or moves at a constant velocity, unless acted upon by an external force.” This is basically saying when something is at rest, it tends to stay at rest, and something that is in motion tends to stay in motion. In marching band, we never tend to stay at rest, because we are always in motion, whether that be playing our instruments, which does require energy, or whether we are moving our bodies by marching or doing a visual, or also even thinking about what we are going to do next. The second law of Newton is, “the acceleration of a body is directly proportional to, and in the same direction as, the net force acting on the body, and inversely proportional to its mass. This is saying that the more force, the more acceleration. This is applying to marching because, you have to have force to do everything. If you don’t have this then we would just be walking all over the field without a care in the world. The way we march is force and the way our feet are moving at a certain tempo is accelerating our movements, putting force to them. Also the way we go to different sets to create objects and shapes in our movements, you have to apply force also, making the pictures sharp. The third law of Newton is, “When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction to that first body.” I believe this is saying that for every action there is an equal and opposite reaction to the other one. This applies to marching band because when you are marching you have to keep straight legs most of the time and, to do that your legs swing kind of like a pendulum, switching the weight of your body from your right leg to your left leg. so this is a force that is an equal and opposite force relying on the other one. Finally there is the physics of simple and complex movement. This has to do with marching band majorly , because this is exactly what we do going from set to set, or object to object. A simple movement is that you are moving in a straight line, we do this many times through our performance, and many times just for practicing sake, for basic marching. There is also complex movements, like going from a specific spot in the field by yourself, then into a curve with other people . also this could be moving from a curve to another curve or a diagonal, which is exactly how it sounds except it’s a diagonal with people. All of these physics applies to marching band majorly and affects our overall performance during our shows and competitions.
