# Friction Calculator

 Calculate static or kinetic friction force. Use this free browser-based friction calculator from XTRAW Tools.

 **Friction Calculator** helps you calculate static or kinetic friction force. Use this free browser-based calculator from XTRAW Tools to compare inputs, estimate results, and plan your next step.

## How to Use the Friction Calculator

1. Enter the required calculator inputs shown in the form.
2. Review the force, energy, motion, mass, velocity, concentration, spring, or chemistry assumptions.
3. Run the calculator, then adjust one input at a time to compare scenarios or check your estimate.

## What This Calculator Helps With

Calculate static or kinetic friction force. It is designed for students, teachers, engineers, physics learners, science users, STEM tutors, and anyone working with mechanics formulas who want a fast, browser-based estimate before relying on a spreadsheet, textbook, lab software, physics software, chemistry reference, professional source, or specialist.

- Coefficient of Friction (μ): 0.4
- Mass (m): 20 kg
- Gravity (g): 9.81 m/s²
- Incline Angle (θ): 0 °

## Common Uses

People use this calculator when they need a quick way to solve physics formulas, compare mechanics assumptions, or check science and engineering estimates.

- **Math Solving:** Solve physics, chemistry, mechanics, concentration, moles, grams, energy, power, or motion equations from entered values.
- **Measurement:** Measure force, energy, power, momentum, concentration, torque, angular velocity, friction, or molar conversion values.
- **Project Planning:** Plan STEM lessons, lab estimates, engineering calculations, study workflows, or science problem-solving tasks.

## Formula or Method

f = μ × N; N = mg·cos(θ)

## Example

**Example inputs:** Coefficient of Friction (μ): 0.4; Mass (m): 20 kg; Gravity (g): 9.81 m/s²; Incline Angle (θ): 0 °

**Example result:** Using the default inputs, normal force is 196.20 N and friction force is 78.48 N.
