1. The problem statement, all variables and given/known data A lab I've performed was measured using forces. As the mass increases, the force does as well. The inclined plane is at an angle of 30 degrees. Now, finding the coefficient, should the kinetic and static friction be decreasing on a plane? I've measured the frictions on a flat surface but the coefficient increases on the surfaces. For example: First )Mass = 0.25kg therefore ForceG =(0.25)(9.8)= 2.45 Force Applied = 1.5N Coefficient = 0.71 Second Mass) 0.33975kg, ForceG=4.21 Force Applied = 2.0 Coefficient = 0.69 2. Relevant equations μ = Force of Friction/Force Normal Force Normal = -mg(cos30) Force Friction = -Fapplied 3. The attempt at a solution I used all the equations I was provided with, and first coefficient: 0.71, then 0.69, 0.68 I was told that when you're applying force on an inclined plane, the Force itself will increase. I'm having troubles understanding WHY the coefficient is going down especially since the mass is increasing.
