Question

The sum of all the forces acting on an object is the
force.

Answer 1

The sum of all the forces acting on an object is called the **net force**. It is the vector sum of all the individual forces acting on that object, determining the object's acceleration according to Newton's second law of motion. If the net force is zero, the object remains in its current state of motion (either at rest or moving uniformly). If the net force is non-zero, the object will accelerate in the direction of the net force.
