1. Rotational Equations
Same as linear kinematic equations, but with rotational variables.

2. Ex: A disk starts from rest and accelerates at 12s-2 for 6. 7 seconds
Ex: A disk starts from rest and accelerates at 12s-2 for 6.7 seconds. Through what angle did it rotate?

3. Connecting angular to linear
Δs = rΔθ
v = rω
t t
Similarly: at = rα
at = tangential acceleration (around)
ar = radial acceleration (away from)

4. example
A wheel on a car has an angular acceleration of 8.5rad/s2. If the wheel has a radius of 13 inches, what is the linear acceleration of the car in feet/s2?
