What is Kinetic Friction?
Kinetic friction is also known as sliding friction or dynamic friction, is a type of friction that occurs when two objects collide. A force that acts between moving surfaces is referred to as kinetic friction. A body moving on the surface is subjected to a force that opposes its progress.
In other words, friction happens when two objects move relative to one another and rub against one another (like a sledge on the ground). The size of the force will be determined by the kinetic friction coefficient between the two materials. The kinetic friction coefficient is indicated by the letter k.
The formula for kinetic friction is: Fk = μk×N
Kinetic Friction Coefficient: μk = Fk/N
Normal Force: N = Fk / μk

Kinetic Friction Examples
Question 1: If the kinetic friction coefficient is 6N and the normal force is 12N, find the kinetic friction.
Consider the problem,
Kinetic friction coefficient, μk = 6N
Normal force, N = 12N
Use the equation for kinetic friction Fk = μk × N.
Fk = 6 × 12
Fk = 72 N
Kinetic Friction (Fk) = 72 N
Therefore, The Kinetic Friction (Fk) = 72 N
FAQs on Kinetic Friction Calculator
1. Is it possible for friction to produce positive results?
Frictional work can never be beneficial. It's always a negative number or a zero.
2. What are the types of friction?
There are four types of friction. They are static, sliding, rolling, and fluid.
3. What are some kinetic friction examples?
The following are some examples of kinetic friction:
- A table that slides across the floor
- On the road, a vehicle is moving.
- Iron is being used to iron fabric.
- Rubbing two hands together.
4. What method do you use to calculate the coefficient of friction?
The coefficient of friction can be calculated in two ways: by measuring the angle of movement or by using a force gauge. The friction coefficient is equal to tan(θ). Where, θ is the angle from the horizontal at which an object placed on top of another begins to move.
