FAQs on Short Trick: Friction Video Lecture - Physics for JEE Main & Advanced

1. What is friction?
Ans. Friction is the force that resists the relative motion or tendency of such motion of two surfaces in contact.
2. What are the types of friction?
Ans. The types of friction are static friction, kinetic friction, rolling friction, and fluid friction.
3. How is the coefficient of friction calculated?
Ans. The coefficient of friction is calculated by dividing the force of friction between two objects by the normal force acting between them.
4. How does friction affect motion?
Ans. Friction can both help and hinder motion. It can provide traction for walking or driving, but it can also slow down objects in motion.
5. How can friction be reduced?
Ans. Friction can be reduced by using lubricants, polishing surfaces, or using materials with lower coefficients of friction.
