If the forces on an object cancel each other out, what is the net force?

When the forces acting on an object cancel each other out, they result in no overall effect on the object's motion. This situation is characterized by a net force of zero. In physics, a net force represents the vector sum of all forces acting on an object. If multiple forces are applied, but they are equal in magnitude and opposite in direction, they will balance each other perfectly, leaving no net force acting on the object. As a result, the object will either remain at rest or continue to move at a constant velocity, adhering to Newton's first law of motion, which states that an object will maintain its state of motion unless acted upon by a net external force.

In contrast, a positive or negative net force would indicate unbalanced forces causing the object to accelerate in a specific direction, and a variable net force implies that the net effect changes over time, neither of which is the case when forces are equal and opposite.
