Unformatted text preview: 198g 13.7 .093 m/s^2-.398 .211 Run 5 198 g 24 1.5 m/s^2-.492 .277 Run 6 198 g 21.6 1.19 m/s^2-.478 .264 Results- As you can see the results look pretty good. The Friction force, as the angle gets steeper, gets bigger and the coefficient stays the same (for the most part). The reason why the coefficient stays the same is because the only factors that determine it are the materials. In our case we had wood and aluminum. Conclusion- This lab teaches us that friction force changes with mass and angle but the coefficient of friction only depends on the material of the block and ramp.
