  1. Apr 18, 2009 #1
    1. The problem statement, all variables and given/known data
    1. The force that propels you forward as you walk across the floor is the force that is exerted by the floor itself. T or F

    2. If you were sitting half as far from your nearest classmate, the gravitational force of attraction between the two of you would be four times as strong. T or F

    3. For any pair of surfaces, the coefficient of static friction between the surfaces is less than the corresponding coefficient of sliding friction. T or F

    2. Relevant equations

    3. The attempt at a solution

    1. Hint: This depends on friction or frictionless surface.
    2. Hint: Gravity acts downward.
    3. Hint: It is harder to get past static friction than kinetic or sliding friction.
