Topics in Rotational Dynamics
1
1. Circular Motion Fundamentals
- Circular motion is accelerated motion due to continuous change in velocity direction
- Angular displacement (θ), angular velocity (ω = dθ/dt), and angular acceleration (α = dω/dt)
- Relationship between linear and angular quantities: v = ωr, a_tangential = αr
2
2. Centripetal and Centrifugal Forces
- Centripetal force is real force directed toward center, providing necessary acceleration
- Centrifugal force is pseudo force experienced in rotating reference frame
- Centripetal force = mω²r = mv²/r in magnitude
3
3. Applications of Circular Motion
- Banking of roads reduces dependence on friction for turning
- Conical pendulum demonstrates circular motion under gravity and tension
- Vehicle on horizontal track: friction provides centripetal force
4
4. Vertical Circular Motion
- Two types: controlled (like giant wheel) and gravity-controlled motion
- Speed varies continuously due to gravity doing work
- Minimum speed at top: v_min = √(rg) for string/track contact
