Question

7. What is limiting friction?​

Answer 1

Answer:

Static friction exists when two objects touch each other at rest. This friction has a limiting value which is called limiting friction, and which is equal to the least force required to move the body from rest. When the external force F is increased, it makes the body just on the verge of moving.

Answer 2

Answer:

A car parked on a hill will not slide down. This is because the value of limiting friction is high enough to ensure that the car is in a state of rest. The limiting force of friction is directly proportional to the mass of the object.
