SUMMARY

The discussion focuses on the various forces acting on a runner in a system modeled using vPython for an extra credit assignment. Key forces identified include normal force (+FN), gravitational force (-mg), drag force (-Fdrag), and friction force (-Ffriction). Additionally, the conversation highlights the importance of considering the inner dynamics of the runner, such as joint efficiency, muscle strength, stride length, tendon elasticity, and foot impact characteristics. These factors are crucial for accurately simulating the physics of running.

PREREQUISITES
  • Understanding of basic physics concepts, particularly forces and motion.
  • Familiarity with vPython for creating animated simulations.
  • Knowledge of biomechanics related to human movement.
  • Experience with modeling complex systems in programming environments.
NEXT STEPS
  • Research the principles of biomechanics to understand muscle dynamics and joint efficiency.
  • Explore advanced vPython features for simulating physical interactions.
  • Study the effects of friction and drag on moving bodies in physics.
  • Investigate the impact of stride length and foot impact characteristics on running efficiency.
USEFUL FOR

This discussion is beneficial for physics students, educators, biomechanics researchers, and anyone interested in simulating human movement dynamics using programming tools like vPython.

Our physics instructor assigned us an extra credit assignment using vPython to make an animated system. The system needs to be something to complex for us to do by hand.

Right now I'm deciding what my topic should be. I think I'd like to do something about a system involving a runner.

My question is what are all the forces that act on a system of someone running around a track. I know there is +FN, -mg, -Fdrag, -Ffriction. I'm certain there is more to consider. Would anyone like to fill me in?

Welcome to PF, Wleemitch.
I can't help you a lot, but you will have factor in the inner dynamics of the runner as well as the outer (just as you would with a car).
Things like joint efficiency, strength of various muscle groups, length of stride, tendon elasticity, foot impact characteristics and stance will all make a difference.
