Example One:a. Angular AccelerationII. Example Two:a. PendulumIII. Example Three:a. Forces acting on an objectCurrent LectureI. Example One:a. What is the angular acceleration of a particle outside a supernova if the radius is 20 km, and the star makes one rotation per second?b. T= 1 second, r = 20 km and plugging those variable into the first equation and converting to m/s gets you V = 125,663 m/sc. Then plugging the velocity and radius into the second equation you get α = 7.9 X 10^5 m/s2T =2 πrVa=v2rThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute. rII. Example Two:a. What is the tangential acceleration of a pendulum at its lowest swinging point? What is its radial acceleration at the same point?i. At = 0, Ar is pointing straight upIII. Example Three:a. What are all the forces acting on a physics book sitting on a desk?i. The normal Force and
