The main difference between Kinetic Friction and Static Friction: Static friction prevents an object from moving while kinetic friction acts on moving objects. Both are crucial for understanding motion on surfaces in CBSE
Kinetic Friction vs Static Friction — Comparison Table
| Basis | Kinetic Friction | Static Friction |
|---|---|---|
| Definition | Friction when object is moving | Friction when object is at rest |
| Magnitude | Lower and constant | Higher and variable |
| Coefficient | Coefficient of kinetic friction (μk) | Coefficient of static friction (μs) |
| When it acts | During motion | Before motion starts |
| Maximum value | Always less than static friction | Greater than kinetic friction |
Key Points
- Static friction must be overcome to start motion
- Kinetic friction opposes ongoing motion
- Coefficient of static friction is always greater
- Both depend on nature of surfaces
