Physics of running

While running on a treadmill one day I noticed that a lot of physics actually took place while running. When one engages in running, you use kinetic energy because your body is now in movement and using energy. When you first begin to jog or start running, your initial velocity is zero meters per second because your body is still at rest and hasn't fully begun to move yet. As you begin to engage in the activity, you begin to jog at a light constant pace which means you maintain a constant velocity. After awhile you might accelerate and gain speed, causing your velocity to increase steadily as well as your distance because your covering more ground. If you wanted to calculate your time while running, you could do so due to the information you know and by using a formula such as v=at. Another important thing to consider is posture and bending your arms and legs while running. Everyone runs with bent knees and arms at about 90 degree angles because its more efficient and makes the individual run faster compared to running with your knees locked and arms stretched out, swinging by your side but not being bent.
