SUMMARY

This discussion focuses on the dynamics of swimming freestyle, specifically the relationship between propulsion force and drag resistance. The user seeks to quantify drag forces experienced both on the water's surface and underwater, as well as the propulsion force generated by the hands and arms. The conversation highlights the importance of understanding these forces to improve swimming speed and efficiency. A request for equations to estimate these variables is made, emphasizing the need for a mathematical approach to analyze swimming performance.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Familiarity with drag force calculations
  • Knowledge of propulsion mechanics in swimming
  • Basic mathematical skills for equation application
NEXT STEPS
  • Research fluid dynamics equations related to drag force
  • Learn about the Bernoulli principle in relation to swimming
  • Explore surface area impact on propulsion in swimming
  • Study the effects of body position on drag and speed
USEFUL FOR

Competitive swimmers, swim coaches, sports scientists, and anyone interested in optimizing swimming performance through a better understanding of propulsion and drag forces.

:rolleyes: Recently I have gained great interst on understanding how I gain speed and move through water while swimming in a race. Using the Freestyle as example I have my body in the water creating drag forces or a form of friction. And I must use my hands and feet(mostly hands/arms) to create surface area to apply force backwards on the water so that it will increase my forward velocity.

When this Push occurs is there any possible way to put numbers on these variables(drag force-on surface and under water, propulsion force-with the surface area and speed and pressure occurring on the pushing surface)

:confused: If anything an equation that I could use to calculate a general estimate of the resistance I receive on the surface of the water compared to the parts of my body the are completely submerged that create drag forces.o:) Any helps?
