Question

state laws of limiting friction, Define and explain coefficients of static and kinetic
force friction​

Answer 1

(ii) The force of limiting friction between two surfaces in contact is independent of the area of contact.

(iii) Limiting friction is directly proportional to the magnitude of normal reaction N between two surfaces in contact, i.e. where n is constant of proportionality and known as coefficient of friction
