Question

2 what is the net force on an object? a the vector sum of all the forces acting on it b the average of all the forces acting on it c the force that is acting on it in the direction opposite of its motion d the difference between the largest and smallest forces acting on it

Explanation:

To determine the net force on an object, we recall the definition of net force. Force is a vector quantity, meaning it has both magnitude and direction. The net force is obtained by considering the vector sum of all individual forces acting on the object.

• Option A states "The vector sum of all the forces acting on it", which matches the definition of net force.
• Option B is incorrect because net force is not the average of forces (average would ignore direction and the vector nature).
• Option C describes a force like friction (opposing motion) but not net force, as net force considers all forces, not just the opposing one.
• Option D is incorrect as net force is not the difference between the largest and smallest forces; it accounts for all forces with their directions.

Answer:

A. The vector sum of all the forces acting on it
