ROTATION OF RIGID BODIES
ANGULAR QUANTITIES
Angular displacement, 
where l is arc length and theta in radian
Angular velocity, ,ω = dθ / dt
Direction determine by right hand rule
Angular acceleration, α = Δω / Δt
Centripedal acceleration, aR = v² / R = (Rω)² / R = ω²R
Tangential acceleration, a tan = dv / dt = Rdω / dt = Rα
Frequency, f = ω / 2π = 1/ T

ROTATIONAL DYNAMICS, TORQUE & ROTATIONAL INERTIA
Torque, T= mR^2a , ∑ T = (∑ mR2a)
Rotational inertia, l = ∑ miRi^2
The rotational inertia of an object depends not only on its mass distribution but also
the location of the axis of rotation
