What are two types of friction?

There are two types of friction: static friction and kinetic friction.
Static friction is the type of friction that keeps an object from moving, even when a force is acting upon it. For example, if you try to push a 1 billion kg block, you won't move it at all because of static friction. Or take a block on a slightly inclined table. Static friction allows the block to stay in place on a slightly inclined table.
Kinetic friction is the type of friction that takes place while the object is moving such as when you are pushing the vacuum around on a thick carpet.
It is important to note that the force of friction, even for the same object, is usually different for both static and kinetic friction.
