1. Static vs Kinetic Friction
10 minutesUnderstand the difference between static and kinetic friction. Learn why it takes more force to start sliding than to keep sliding, and how static friction self-adjusts.

2. The Friction Equation (f = μ N)
12 minutesMaster the relationship between friction force, coefficient of friction, and normal force. Practice calculating friction on flat surfaces with varying applied forces.
3. Friction on Inclined Planes
15 minutesApply friction to ramp problems. Decompose gravity into parallel and perpendicular components, find the critical angle, and solve for acceleration with friction.
4. Angled Forces and Multi-Object Friction
15 minutesAnalyze how pushing or pulling at angles affects normal force and friction. Solve stacked-block problems and determine maximum acceleration before sliding.
5. Air Resistance, Terminal Velocity, and Applications
12 minutesExplore speed-dependent drag, terminal velocity, ABS braking, turntable problems, and real-world engineering applications of friction.
