Physics Extended Essay

  1. Mar 13, 2013 #1
    Hello!!
    I am doing my Extended Essay in physics. Extended Essay is a formal research on a topic and its about 4000 words. My topic is ' How does depth of water on the road and the temperature of the road affect the coefficient of kinetic friction'. My teacher says I cannot effectively control the variables, can anyone give some advice on the topic. I have access only to my high school lab.

    Welcome to the PF.

    Are you able to separate those two effects into two subjects, or do you need to have both water on the road and variable temperature at the same time?

    What kind of reading have you been doing so far to give you ideas on how to proceed? It would seem that searching for information on hydroplaning would be helpful. And separately searching for information about tire traction versus pavement temperature should help some too.
