The example for Newton's Law

The friction have two different kinds. One is Kinetic friction and the other one is Static friction.

The first one is Static friction. Static friction is how many force you use, the friction can increase,too. And static friction can effect with some reasons, like surface, mass...... The Static friction have minimum friction, but we call it maximum Static friction. Example, you want to move the box on the table. If you use 80(N) on this object. The box's friction can increase 80(N).

The second one is Kinetic friction. When object move to result friction is the Kinetic friction. When the object surmount the friction(Kinetic friction)and keep moving. The friction can be decrease. When the force surmount the maximum Static friction, that the Kinetic friction. For example, the car wheel. If the car want to move, it force should surmount the maximum Static friction. That the why car can move.
