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

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?

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

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?
