Question

If a person wants to move a heavy box across the room, what is required to get the box in motion? apply any force apply a force greater than the starting friction only a pushing force will work only a pulling force will work

Answer 1

The Correct Answer Is Apply A Force Greater Than The Starting Friction.

Answer 2

if a person want to move a heavy box across the room, he must apply a force that is greater than starting frictional force acted on the heavy box in order to get the box in motion. the frictional force is equal to coefficient of friction times the normal force, and normal force is approximately the weight of the object. so the force that must be applied must be greater than the wieght of the object.
