Question

1. the force needed to start a box moving from rest on a horizontal surface is _. clear all less than the maximum force from static friction equal to the normal force greater than the maximum force from static friction equal to the force from gravity

Explanation:

Static friction resists the initiation of motion. The force required to start an object moving from rest on a horizontal surface must overcome the maximum static - friction force. So, the force needed to start the box moving must be greater than the maximum force from static friction.

Answer:

C. Greater than the maximum force from static friction
