It only moves forward because there is a net force forward.
Let us note that when an object is acted upon by a system of forces, the object only moves in the direction of the net force.
We have an animal acted upon by the following forces;
- 5 N forward
- 4 N backward
- 10 N upward
- 10 N downwards
The upwards and downwards forces are exactly balanced so the animal neither moves upwards or downwards.
However, the animal does move forward because there is a net force that pushes the animal forward.
