Two weeks ago we were learning about the two different frictions, which are the kinetic and static friction. So last week we did a mini-lab to further our understanding of the topic. This is the data of the lab we did:
Sample data table:
| Material | Trial 1 angle | Trial 2 angle | Trial 3 angle | Average angle | Coefficient of static friction |
| Sandpaper 1 | 48 | 48 | 48 | 48 | 1.11 |
| Sandpaper 2 | |||||
| Sandpaper 3 | 50 | 46 | 47 | 47 and 2/3 | 1.1 |
| Sandpaper 4 | |||||
| Sandpaper 5 | |||||
| Wood | 34 | 31 | 32 | 32 and 2/3 | 0.64 |
| Cloth | 34 | 34 | 34 | 34 | 0.67 |
