Kinetic Vs. Static Friction

In the past few weeks, in physic class, we were learning about the Newton Laws, static equilibrium, and friction. On the Wednesday last week, we did a small lab that cover friction and most importantly, the coefficient of static friction. We would use different objects with different type of surface, and then set a paperclip box on it. We would record the angle when the bow start to move. We had a lot of fun while also learning new concepts. The lap ma look simple, but I enjoy doing it.
