The problem was to determine the coefficient of kinetic friction between a block of wood and a metal ramp. We had to see if the coefficient would change as the angle increased. The first experiment was to change the mass of the block to find the coefficient. In our experiment, we had to change the angle of the ramp that the block had to slide down. We had a block of wood slide down the ramp at a certain angle. After we recorded the motion, we changed the angle. We did this three times to get three videos. We made three videos using VideoRecorder, one for each angle change. We analyzed these videos using VideoTool to find the acceleration of the block going down the ramp. Theoretical Calculation: Our group predicted that the coefficient of friction would be the same, no matter what angle the ramp is at. We knew the normal force had to do with the frictional coefficient.
