The Physics of Track and Field

Reason: The reason I chose to do track and field was because I enjoy the sport and its easy to see where there is physics within it. I myself did (and might to again) track, and liked it alot.

Description: Track and field is/are a sport(s) performed indoors or outdoors and made up of several events, as running, pole-vaulting, shot-putting, and broad-jumping.  Pole-vaulting is the act of using a spear like object to launch oneself over a bar at a preset height.  Shot-putting is a sport in which a thrower takes a heavy metal ball, called a shot-put, and has to see how far they can throw it.  Broad-jumping is the act of seeing how far a runner can jump into a pit of sand when set at a certain distance.

Physics Explanations: Three physics concepts involved in track and field are Newton's Laws of motions, momentum, and kinematics. Newton's Laws focus on all aspects of track and field, where as momentum is mostly field, and kinematics is mostly track. Movements such as running and jumping can be analyzed using several different equations. Each represent different parts of the activity. For example, if a runner is running at 7m/s for 10s, we can use the equation Δx=vΔt to figure out how far he is running.

Mathematics: Several physics equations used within the sport are ΣF=ma, p=mv, Σpi=Σpf, and many more. These are used to solve anything from how fast and far someone is running, to how much momentum they have after a pole-vault.
