hi,
i am taking this physics course through correspondance and don't have anyone to help me. i am supposed to do a lab on measuring coefficients of friction. purpose of the lab is to determine whether tread design affects the coefficient of static friction for running shoes. i am supposed to use a wooden board, a meter stick and some shoes. i need to write a procedure myself..so here is what i have done so far... i took 4 pieces of shoes noted their make and type, then i measured the horizontal length of wooden board, also assumed mass of shoes...then i placed a shoe on the wooden board and lifted it unlti the shoe began sliding and then i noted the verticl length as well...
now i had to write a hypothesis and a prediction before i started anything. so, i say in my hypothesis that yes tread design as well as shoe design affects the coefficeint of static friction. both are made in a way to have maximum coefficient of static friction inorder for a person or object to have firm grip and don't just slip...
i need help with this, i am sure i could say more than that...thanks in advance everbody.
