Final answer:
Net force is the term used to denote the vector sum of all forces acting on an object, it regards both magnitude and direction of all the individual forces. It affects an object's motion, causing acceleration in the direction of the net force.
Step-by-step explanation:
The term used to describe the vector sum of all the forces acting on an object is known as the net force. In physics, vectors are quantities that have both magnitude and direction. When you sum up all the forces acting on an object, taking into account their magnitude and direction, the resulting force is the net force on that object. For instance, if there are two forces, 10N to the east and 5N to the west acting on an object, the net force is 5N to the east. The net force affects the object’s motion, and according to Newton's second law of motion, it will cause an acceleration in the direction of the net force.
