FAQs on Angle of Friction Video Lecture - Physics for JEE Main & Advanced

1. What is the angle of friction in mechanics?
Ans. The angle of friction, also known as the angle of repose, is the maximum angle at which an object can rest on an inclined plane without sliding down.
2. How is the angle of friction related to the coefficient of friction?
Ans. The angle of friction is related to the coefficient of friction by the equation: tan(θ) = μ, where θ is the angle of friction and μ is the coefficient of friction.
3. How does the angle of friction affect the stability of an object on an inclined plane?
Ans. The angle of friction determines the maximum angle at which an object can rest on an inclined plane without sliding. If the angle of the plane exceeds the angle of friction, the object will start to slide.
4. How can the angle of friction be calculated in a real-life scenario?
Ans. The angle of friction can be calculated by measuring the angle at which an object starts to slide down an inclined plane and using the equation tan(θ) = μ, where θ is the angle of friction and μ is the coefficient of friction.
5. Can the angle of friction be greater than 90 degrees?
Ans. No, the angle of friction cannot be greater than 90 degrees as it represents the maximum angle at which an object can rest on an inclined plane without sliding.
