The Mu of a Shoe

April 24, 2018

These are spring scales.  They are used to measure the weight of things, and the forces on things.

We measured the weight of the shoe, and then we pulled he shoe to determine the force of friction on the shoe.  We added mass and repeated the procedure.

We noticed the force to get the shoe moving is bigger than the force to keep the shoe moving.

All of these forces are bigger when the mass of the shoe is bigger.

We tried all of this experiment again but on a wet floor.  The goal is to determine the coefficient of friction between the show and dry floor and the shoe and wet floor.
