What is friction? Define coefficient of static friction and coefficient of kinetic friction. Give the necessary formula for each. |
|
Answer» 1. The property which resists the relative motion between two surfaces in contact is called friction. 2. The coefficient of static friction is defined as the ratio of limiting force of friction to the normal reaction. Formula: μs = FL/N 3. The coefficient of kinetic friction is defined as the ratio of force of kinetic friction to the normal reaction between the two surfaces in contact. Formula : μs = Fk/N |
