Chapter 9 : Rotational Motion, Angular Quantities, Solving Problems in…
-
Angular Quantities
- Angular displacement, θ (rad)
- Angular velocity, ω (rad/s)
- Angular acceleration, α (rad/s²)
v=Rω
- R increase, v increase
- Object farther move faster.
- tangential a = Rα
- centripetal a = ω²R
- total linear acceleration = √(a-tangential² + a-centripetal²)
- Frequancy, f=ω/2π (Hz)
- Period, T= 1/f
