Question

Write down two factors on which the magnitude of frictional force depends
between two surface

​

Answer 1

Answer:

The magnitude of frictional force depends on the surfaces that are in contact and the force pushing them together. This force is usually related to the weight of the object or objects. Surfaces that appear smooth can be rough at the microscopic level, having many ridges and grooves.

Answer 2

Answer:

Two factors are:

$1.\mu$

$2.Normal force(N)$

$\mu\:refers\:to,how\:rough\:is\:the\:surface$

$Normal\:Force\:is\:generally\:<strong><em>mg</em></strong>\\</p><p>(m-mass,g-9.8m{s}^{2})$
