Physics Tool
Friction Calculator
Calculate the force of friction (Ff) acting on an object based on the coefficient of friction and normal force.
Friction Force (Ff)
40.00
Newtons (N)
Σ The Formula
Ff = μ × Fn
Real World Examples
Rubber on Concrete
μ=0.6, Fn=500N → Ff = 300N.
Ice Skating
μ=0.05, Fn=600N → Ff = 30N.
# About This Calculator
Frictional Force is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
The calculation requires two inputs:
- Coefficient of Friction (μ): A dimensionless number representing the "grippiness" between two surfaces.
- Normal Force (Fn): The perpendicular force exerted by a surface on an object (usually related to gravity/weight).
How To Use
- Enter the **Coefficient of Friction (μ)**.
- Enter the **Normal Force (Fn)** in Newtons.
- The **Frictional Force (Ff)** is displayed in Newtons.
- Toggle between Static and Kinetic coefficients depending on whether the object is moving.
Frequently Asked Questions
Static vs Kinetic Friction?+
Static friction (μs) acts on objects that are not moving. Kinetic friction (μk) acts once the object starts to slide. Typically μs > μk.
Is Friction Calculator free to use?+
Yes, Friction Calculator on Matheric is completely free to use. We believe in accessible education and utility for everyone.
How accurate is Friction Calculator?+
