Final answer:
The name of the force that is a combination of all forces acting on an object is the net force.
Step-by-step explanation:
The name of the force that is a combination of all forces acting on an object is the net force. When multiple forces act on an object, the net force is calculated by adding together all of the forces. The net force determines the overall motion of the object. For example, if the net force is zero, the object will be at rest or moving at a constant velocity.
