What is the net force on an object

at rest?

- - If it's at rest, then it's not accelerating.

- - If it's not accelerating, then the net force acting on it is zero. (See Newton's 2nd law of motion.)

Net force equals 0

Explanation:

Newton's first law states that an object at rest tends to remain at rest, and an object in motion tends to remain in motion with a constant velocity (constant speed and direction of motion), unless it is acted on by a nonzero net force. Note that the net force is the sum of all the forces acting on an object.
