Physics of Gymnastics :: physics sport sports gymnast gymnastics

Gymnasts use natural philosophy everyday. As a gymnast I neer realized how practically physics went into every motion, every back handspring, every mistake on the bars. If gymnasts were physicists (or at least knew more about physics) they would be better equipped to get over the difficult aspects of gymnastics. As a gymnast I learned the motions that were necessary to complete the tricks that I was working on, and as a coach I taught others the same. I never truly understood why a particular angle gave me a better back handspring or why the angle that I hit a springboard at really mattered when completing a vault. We are going to explore some of the different apparatuses in gymnastics and a few of the physics laws that are involved in them. We will not even barely scratch the surface of the different ways that physics lot explain gymnastics.Newtons Laws Newtons Laws can be found in the textbook, Physics for Scientists and Engineers by Serway.Newtons First Law An i ntent remains at rest, or in motion, unless an external force acts upon it.Newtons bite Law The acceleration of a body or object is directly proportional to the net force acting on the body or object and is inversely proportional to its mass. F = ma Newtons Third Law For every action force, there is an equal and opposite reaction force.The Floor There are many aspects of physics found on the floor. The gymnast performs on a floor that measures 12 x 12 meters, with an additional safety border of 1 metre. The doing area must have a surface elasticity, to allow for power during take-off and softness for landing. (FIG) The surface elasticity found in the floor mat gives the gymnast wasted bounce which increases her momentum. Lets examine a basic stunting run. All three of Newtons Laws can be seen in this one tumbling run. We can see Newtons initiatory law before the gymnast takes even one step. Until she takes a step, the gymnast is at rest. When she is ready to tumb le the gymnast applies the force. A gymnast takes a running start when approaching a tumbling run, and as she is moving across the floor she is increasing her momentum. This is a demonstration of Newtons second law.
