Sliding fraction is ...... the limiting fraction?
Answers
ANSWER:
SLIDING FRICTION IS LESSER THAN LIMITING FRICTION.
Explanation:
This is due to the fact that the coefficient of static friction is greater than the coefficient of kinetic friction. In this case what you are referring to as limiting friction is the same as static friction, or the friction experienced by a static object that is having force applied to it.
Coefficients of friction come into play when you consider the formulas for static and kinetic friction: force of friction= coefficient of friction(static or kinetic) times either normal force or force applied to the object(normal force for static, force applied for kinetic). All of this is based on the idea that more force is required to move an object from rest than it is to keep a moving object going. Consider the case of pushing a car. The initial push while it is at rest is the hardest, but once it starts moving it is easier to push.
