Coefficient of friction

  1. Sep 26, 2009 #1
    Ok, i have a question that i need someone to put into simple terms, i kind of understand why, but it would be helpful if someone could explain it more simply.

    How does the coefficient of friction associated with starting an object's motion compare to the coefficient associated with maintaining its motion?

    Its something like it requires less force to move an object already moving and such.. but i still want a more explaining answer.

    Thanks

    I think you've got the idea all right. But the answer requires that you say clearly whether the dynamic coefficient of friction is larger or smaller than the static coefficient of friction. As a check on your deduction, you could check some coefficients in a table.
