Transcript of Math and Science Behind Gymnastics

The Math & Science Behind Gymnastics Gymnastics is
a very athletic
sport that includes Jumping Stretching Flipping Twisting By:Allison Mitchell Many of the skills that gymnasts perform fit in to Newton's Laws of Motion Newton's First Law of Motion Newton's Second Law of Motion Newton's Third Law of Motion The object at rest, being the gymnast, will stay at rest until it has a force to move, such as a swing on the high bar Think about the gymnast's weight (mass). Heavier gymnasts need more force to complete their skills. There is an And the more force the gymnast uses, the faster they go and the more energy is exerted For every action there is an equal and opposite reaction On beam, the gymnast is exerting the same amount of force as the beam as well as an opposite force So what does all this have to do with math and science? Well... Centripetal force A force that acts on a body moving in a circular path and is directed toward the center around which the body is moving. This is used in bars during almost every skill To find out how kinetic energy affects the vault, the velocity of the run must me calculated Now that velocity equals 6.25 m/s, we must determine the kinetic energy So what does this tell us? The more kinetic enery and momentum a gymnast has... the more air time the gymnast wil have and the quality of the vault will be better Vault looks like this And a front handspring half looks would look like this... During the vault, the gymnast runs, jumps on the spring board, and then "pops" off the vault table You can then get a vault that looks like this We can also determine the momentum The gymnast builds up her momentum for her double flyaway dismount THE END
