Web22 okt. 2024 · The ratio between limiting friction and normal reaction is slightly less when the two surfaces are in motion. 7. The force of friction is independent of the velocity of sliding. The above laws of solid friction are also called laws of static and dynamic friction or law of friction. ← Prev Question Next Question → Find MCQs & Mock Test Web13 apr. 2024 · The magnitude of the force of friction is exactly equal to the applied force. The magnitude of the maximum static friction bears a constant ratio to the normal reaction between the two surfaces. Laws of Friction for Dynamic: Force of friction always act in a direction opposite to that in which the body tends to move.
