Conclusion In order for our group to come to some of our major conclusions, we first needed to find what really has effect on Kinetic Friction. We first came to find out that velocity along with surface area have no affect whatsoever on the amount of Kinetic Friction that is being placed on the block. Next, we tested two different types of surfaces to see how each one compared. The two different types of surfaces we used were the “smooth and rough” sides of a dry erase board. We found that the type of surface does impact the amount of friction. Since we came to the conclusion that the type of surface has an impact on the friction, we now were able to begin testing with different weights. After conducting ten tests for each

Unformatted text preview: surface (both surfaces were given the same tests) using different weights, we found some interesting results. Here were the equations we found: Force of K Friction= (0.2271 N/N) Normal Force + 0.2028 N Surface #1 (Rough) Force of K Friction= (0.2361 N/N) Normal Force + 0.00661 N Surface #2 (Smooth) As shown by our equations, the Rough surface had a slightly less slope but had a larger Y-intercept. After discussing all of the groups equations in class, we found that the Rough surface should have had a larger slope along with a larger Y-intercept. Since they are very close, we would not consider this a very significant error....
