Question

an unbalanced force acting on an object must overcome ____ before the object will move. static friction neutral weight microscopic texture sliding friction

Explanation:

Static friction is the force that keeps an object at rest. An unbalanced force must overcome this force to set the object in motion. Once the object is moving, sliding friction comes into play. Neutral weight is not a force that resists motion, and microscopic texture is a property of the surface, not a force to be overcome for motion.

Answer:

A. static friction
