1. Draw the Objects:

* Draw a simple object, like a box, to represent the thing being pulled.

2. Represent the Forces:

* Force 1: Draw an arrow pointing to the right, labeled "20 N". This represents the force pulling the object to the right.

* Force 2: Draw an arrow pointing to the left, labeled "16 N". This represents the force pulling the object to the left.

3. Show the Net Force:

* Calculate: The net force is the difference between the two forces: 20 N - 16 N = 4 N.

* Direction: Since the force of 20 N is larger, the net force is in the direction of the 20 N force (to the right).

* Arrow: Draw a longer arrow to the right, starting at the object and ending at the point where the net force acts. Label this arrow "4 N".

Example Diagram:

```

20 N --> [ Box ] <-- 16 N

--> 4 N

```

Explanation:

* The diagram shows that the object is being pulled to the right with a net force of 4 N. This means the object will accelerate in that direction.
