B Is it possible to calculate how much force is exerted on the ground and shoe midsole by your body while you run?

I believe it is not only about weight because you still push into the ground while you run, so it's gotta be more than that. I thought it could be calculated by a simple electronic scale experiment like you will push on them with your foot and collect the reading, however, it seems to be more than that or even nothing of it. For my research, I need to find out whether the material and size of the midsole affect your speed while running from a physics point of view, if you all have any ideas on how I can do that please feel free to leave your thoughts and suggestions.

Welcome to PF.

What have you found so far with your searching? I did a simple Google search on Physics of Running and got lots of hits. The first one looks to have lots of info you can read through:

Also, is this question for your schoolwork? If so, I can move your thread to the schoolwork forums for you.

I came up with an equation that total force input on the ground is your total muscular force minus how much force it took to squish the midsole, and total force output from the ground is the same things but added up, probably wrong

It is for my extended essay (4000 research paper, necessary part of IBDP curriculum, but is not considered homework

is not considered homework

By whom?

 

[midiya]

by everyone, it is a project we have to complete by the end of the course

A project is schoolwork. Arguing that this does not belong in the homework / schoolwork forms will not get you very far,

In those forums, there is a template to remind you to show your work, but no matter where it is posted, as @berkeman said, you need to show your work. We are not going to do your work for you. And "I came up with an equation" is not showing your work. What equation? Where did it come from? Why did you select it? What have you done to determine if it is correct or not? That is showing your work.

Moving your thread to the schoolwork forums for you now. And as V50 says, we need to see your detailed work in order to provide you our tutorial assistance.

I guess he lost interest.

I guess he lost interest.

No, no, he's just very busy reading through all the websites that I suggested. That simple search yielded a *lot* of information...
