We did a lab with friction and tension/normal, and I have a few questions. We used a shoe on different surfaces. Here are my questions:
1. What is the relationship between the pulling force (required to move the shoe at constant speed) and the weight of the shoe? *
2.What factors affect the force required to pull the shoe across a surface? *
3.What is the relationship between the roughness of the surface and the force required to pull a shoe? *
