1It is the friction force and it is parallel to the surface.
2Anyway, perhaps you see an important aspect of the friction force.
3Fortunately, we have a pretty good approximation for the friction force.
4When two surfaces rub against each other, why is there a friction force?
5This model says that the surface area doesn't have an impact on the friction force.
6The friction force also depends on the normal force.
7Since the friction force and the displacement are in the same direction, the work is positive.
8In this case, the friction force (on both his hands and feet) push up.
9The only difference would be that the friction force would be replaced by some other force.
10So for our energy perspective on this problem let's just say the human provides the friction force.
11That's because you need the largest friction force because the pole pushes only in the horizontal direction.
12The friction force is essentially from me (the rider).
13Here is a fairly normal model for sliding friction : This is just the magnitude of the friction force.
14The story force wants to go forward and the " friction force" of challenge tries to hold story back.
15This means that the magnitude of the friction force will be: With this, I can eliminate the friction force from the two equations.
16The usual model for the static friction force (for a non-sliding tire) says that this friction force is proportional to the normal force.
