Question

Give a brief description of kinetic friction formula​

Answer 1

Answer:

Kinetic Friction Formula

Fk = force of kinetic friction. μk = coefficient of kinetic friction. η = normal force (Greek letter “eta”)

Answer 2

$\huge\tt{\underline{Answer :- }}$

The most straightforward kinetic friction definition is given as the resistance towards the motion caused by the contact between a surface and the moving object against it. The force of kinetic friction acts in the oppose of the moving object. Therefore, if we push something forward, friction will push it backward.

The kinetic friction force only applies to an object that is moving and it is otherwise known as sliding friction. Another major type of friction between the solids is static friction. It is the resistance to motion caused by the friction between a still object and some surface. The coefficient of static friction is generally found larger than the coefficient of kinetic friction

Kinetic Friction Formula is given as:

Fk=μkFn

Also, if the problem involves a horizontal surface and no other vertical forces are acting i.e., Fn=mg,

Fk = Force of kinetic friction

μk= Coefficient of sliding friction or kinetic friction

Fn= Normal force, equal to the object’s weight

m = Object’s mass

g= Acceleration due to gravity
