The limiting value of static friction depends on: *

1 point


The limiting value of static friction depends on: *
1 point
​

Answer 1

the limiting value of of static friction depends on two surfaces

Answer 2

The limiting value of static friction depends on the following factors:

• The static coefficient of friction between the pair of surfaces in contact.

• The normal reaction between the two surfaces.

$\boxed{ \sf{friction = \mu \times N}}$

The limiting value of static friction is the max value of static friction present between the two surfaces. If the applied force becomes greater, then the object starts moving.
