Re: Coefficient of friction of tetra

you could determin this experimentally:

get a force meter (mechanical bathroom scales will work too.....)

measure force at the moment it starts to move....
Fmax=mu_s*N
so:
mu_s=Fmax/N


and once it's moving:

mu_k=Fmax/N


theorecticly you should get two different values, but i don't think you could notice the difference....
