Question

Explain the terms : (i) Coefficient of static friction

(ii) Coefficient of kinetic friction​

Answer 1

Answer:

It is either the coefficient of static friction , or the coefficient of Dynamic friction .The coefficient of static friction is the friction force between two objects when neither of the objects is moving. ... A value of 1 means the frictional force is equal to the normal force.

The coefficient of kinetic friction is the ratio F/w or mg/Mg , or simply m/M. Based on the data you enter, if the ratio m/M is exactly equal to the selected μ, no motion will occur. To cause motion, you need to slightly increase m, the hanging mass, by 0.1 gram, for example.
