Friction Calculator is a clean, professional, and lightning-fast Android app designed for students, teachers, engineers, and physics enthusiasts to calculate frictional force using the fundamental formula:
F = μ × N
(Frictional Force = Coefficient of Friction × Normal Force)
No complicated menus. No bloated features. Just accurate physics in seconds.
Key Features
Instant Calculation – Enter μ (coefficient of friction) and N (normal force), tap Calculate, and get results in Newtons (N).
Smart Input Validation – Prevents errors with real-time checks for empty, invalid, or negative values.
Precision Output – Results displayed with 2 decimal places for professional accuracy.
Clean & Modern UI – Built with Material Design and ConstraintLayout for a smooth, intuitive experience.
Perfect For
High School & College Physics Students
AP Physics / JEE / NEET Preparation
Engineering & Mechanics Problems
Quick Reference in Labs or Classrooms
How to Use
Enter the coefficient of friction (μ) – e.g., 0.3 for wood on wood
Enter the normal force (N) in Newtons – e.g., 150
Tap Calculate
View result: Frictional Force: 45.00 N
