Question

For an object at rest, the normal force equals the gravitational force. What is the sum of these forces called?

[ ] Net force
[ ] Unbalanced force
[ ] Inertia
[ ] Potential force

Answer 1

Net force >>> the vector sum of forces acting on a particle or body

Answer 2

Sum of these forces is called net force.

Step-by-step explanation:

When an object is at rest, the forces acting on it are normal force and gravitational force. The normal force act in upward direction while the gravitational force acts in downward direction.

In this case, for an object at rest, the normal force equals the gravitational force. The sum of these forces is called net force. The overall forces acting on the object in any direction is called net force.

Hence, the correct option is (a) '' net force''.
