Need help with physics project involving force of friction of various surfaces.

  1. Hey I have to do a project in which I am going to roll a soccer ball across different surfaces such as turf, grass, concrete, etc... and calculate the force of friction of each of these surfaces. I believe that i need to find the Initial force of the ball, then the final and subtract to find the force of friction. The thing is i have no idea how to conduct the actual experiment.

  3. u can find the force of friction on the three different surfaces by knowing the cofficient of friction of the three surfaces and finding the weight of the ball & apply the formula.
