Question

What is the limiting force of friction?

Answer 1

The limiting force of friction:

1. The maximum friction force that comes into play when the body just starts moving is the limiting condition of static friction.
2. It is also called limiting friction.
3. It is the product of the Normal force and coefficient of limiting friction.
4. Mathematically, it can be expressed as

$F=\mu .N$

where, $$\begin{gathered} \mu =coefficientoffriction \\ N=Normalforce \end{gathered}$$

4. The limiting friction is always opposite to the motion of the object.
