Friction arises due to Contact between surfaces.
Friction is a force that opposes the relative motion between two surfaces in contact. It arises due to the contact between two surfaces. When two surfaces are in contact, the irregularities on their surfaces interlock with each other. This interlocking of the two surfaces results in the force of friction.
Friction is caused by the roughness of the surfaces in contact. Even the smoothest of surfaces, when viewed under a microscope, have tiny hills and valleys. When two surfaces are in contact, these hills and valleys interlock with each other, resulting in friction.
Types of Friction:
1. Static friction: Static friction is the friction that acts on an object when it is at rest. The force required to overcome static friction is called the force of static friction.
2. Kinetic friction: Kinetic friction is the friction that acts on an object when it is in motion. The force required to overcome kinetic friction is called the force of kinetic friction.
3. Rolling friction: Rolling friction is the friction that acts on an object that is rolling. It is less than the force of static friction and the force of kinetic friction.
Conclusion:
Thus, friction arises due to the contact between two surfaces. The roughness of the surfaces in contact causes the interlocking of the two surfaces, resulting in friction. Friction can be of three types - static friction, kinetic friction, and rolling friction.
