Normal and Kinetic Frictional Force March 7, 2006 Performed by : Mitch , Crystal Cooling, and James Edmonson TA: Jingshan Zhang Problem: The problem presented in this lab is to see if the Kinetic Frictional Force and the Kinetic Coefficient of Friction of wood on aluminum changes for different angles of the board and different masses of the block. We took a aluminum track and set it on the table, taking video of the block as it slid down the track under different situations. Using these videos we calculated the acceleration and found the quantities we were searching for. Prediction: We predicted that as the angle of the track changed, the amount of Frictional Force would go down, due to the fact that the Kinetic Coefficient of friction multiplied by the Normal force (N=mg*cos θ ) is proportional to the Frictional Force. As for the mass of the block increasing, we predicted that the frictional force would go up, because of the same reasons, the Normal force multiplied by the Kinetic Coefficient of friction is equal
