Revision Notes — Circular Motion
Key concepts, formulas, and definitions from Circular Motion for JEE Mains Physics preparation.
Key Topics to Revise
Kinematics of Circular Motion
- In circular motion, velocity direction continuously changes even if speed is constant
- Angular velocity (ω) = dθ/dt, measured in rad/s
- Linear velocity v = rω, where r is radius of circular path
Dynamics of Circular Motion - Centripetal Force
- Centripetal force = mv²/r = mrω² (always toward center)
- Centripetal force is not a separate force but net radial component of all forces
- Real forces providing centripetal force: tension, friction, normal force, gravity components
Banking of Roads and Friction in Circular Motion
- Banking eliminates dependence on friction for safe turning at designed speed
- Banked road: outer edge raised above inner edge by angle θ
- Three cases: friction only, banking only, friction + banking combined
Motion in Vertical Circle
- Particle attached to string moving in vertical circle under gravity
- Energy conservation: ½mv² + mgh = constant throughout motion
- Three possible scenarios based on initial speed at bottom
