Friction is a push force. When one object pushes one direction on an object the other object pushes the opposite direction. The harder an object is pushed against another the more friction there is.

Increase the normal force, or push down on it more (add more weight). friction = μ normal force μ is the coefficient of friction which is different for different surfaces
Push it, or pull it. You may have to push hard enough to overcome a force of friction.
The direction of the friction force is always opposed to the movement. If I push my desk to the north, the friction force will be to the south - and if I don't push hard enough, it won't budge.
force
A force is a push or pull on an object some ex are friction
they all have something to do with force
examples of contact forces are : friction, tension, normal force
When you push a book, it stops because of the force you are applying to it. The friction between the book and the surface it is resting on counteracts the force you are applying, bringing the book to a stop.
If it doesn't move, it doesn't accelerate; therefore the net force must be zero.

If it doesn't budge, the net force must be zero. What usually happens is that there is a force of friction that opposes the push or pull; as you pull harder, the force of friction increases. At a certain treshold, there is not enough friction (it can only increase to a certain level), and the object starts moving.
Through push and pull and the other force is friction
