The net force on the box is the difference between the applied force and the force of friction. In this case, the net force on the box is 13 N (20 N - 7 N) in the direction of the applied force.
Sliding Friction If you push hard enough on the cardboard box filled with books, it will start sliding. If you stop pushing after the box starts sliding, it will slow down and stop. The force that acted on the box to slow it down was sliding friction. Sliding friction is the force that opposes the motion of two sliding surfaces in contact. Sliding friction exists between all sliding surfaces that are touching, such as the surfaces of the moving parts in a car's engine.
An example of sliding kinetic friction is pushing a box across the floor. As the box moves, there is friction between the box and the floor opposing its motion. This friction force must be overcome by applying a force in the direction of motion.
it is usually greater than static friction
Sliding your hands together is an example of sliding friction.
The force that keeps a box from sliding down an angled conveyor belt that slopes upward is friction. Friction acts in the opposite direction of the box's movement, preventing it from sliding down the slope.

Examples of SLIDING FRICTION is pushing a heavy rock in your path, or moving a box on the floor.

The force that keeps a box from sliding down an angled conveyor belt that slopes upward is friction. Friction acts in the opposite direction of the box's movement, preventing it from sliding down the slope.
As you push a cereal box across a tabletop, the sliding friction acting on the cereal box acts in the direction opposite of motion.
The force that prevents a heavy box from sliding along the floor when you push on it is friction. Friction is the resistance force that occurs when two surfaces come into contact with each other. It acts in the opposite direction of the applied force, creating a “grip” that keeps the box from sliding.
static friction
The force that makes it hard to pull the box is friction. Friction is a force that opposes the motion of objects sliding against each other.
The type of friction pushing a box along the floor is kinetic friction. This frictional force opposes the motion of the box and arises between the box and the floor due to their contact and relative motion.
Well, depending on which way you are pushing, it could be one of three forces. If you are pushing along a table, then it is friction that is preventing the box from moving (or more accurately, static friction). If you are pushing the box down into the table, then it is the normal force that is at work. If you are pushing into the air, then it is gravity.
