Laws of limiting friction |
| Answer» Laws of kinetic or limiting friction1. The direction of limiting frictional force is always opposite the direction of motion.2. Limiting friction acts tangential to the two surfaces in contact.3.The magnitude of limiting friction is directly proportional to the normal reaction between the two surfaces. 4. The limiting friction depends upon the material, the nature of the surfaces in contact and their smoothness.5. For any two given surfaces, the magnitude of limiting friction is independent of the shape or the area of the surfaces in contact so long as the normal reaction remains the same. | |
