FAQs

Question: What is the difference between static and kinetic friction?
Answer: Static friction acts on an object at rest and prevents it from moving, while kinetic friction acts on an object in motion and opposes its movement.

Question: How do I calculate centripetal force?
Answer: Centripetal force can be calculated using the formula F = mv²/r, where m is the mass, v is the velocity, and r is the radius of the circular path.
