Question

define coefficient of friction???
answer plz​

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.

Explanation:

Friction coefficient is a measure of force generated by moving surfaces of two identical fabrics in contact at standard rate and pressure

Answer 2

$\Large\bold{\underline{\underline{Answer:-}}}$

Coefficient of friction is a dimensionless quantity whose value is equal to the ratio of the frictional force between the surfaces in contact and the force pressing them together (which is also the normal force).

Coefficient of friction = Frictional force/Normal force

Dependence of coefficient of friction :

• Type of substance in contact.
• Temperature of surfaces in contact.
• Roughness of the surfaces in contact.
• Velocity of the surfaces in contact.
