Useful Equations and Relations: Rotational Motion rad)- As/r lilclhiell hat the answer you found was checked by you and whether the solution appears to be reasonable or not. (rad) deg)/180 2t rad Irev 1. Consider a clockwise-rotating object, such as the odd-shaped one shown below. The large black dot near the center of the obiect represents the point around which it is rotating, and the line through that point is called the axis of rotation of Pi and P2 represent arbitrary points on the object's surface. Pi (a) Describe the trajectories of the points Pi and P2. What is different about these trajectories? (b) Will the points Pt and P2 be moving with the same linear velocities? If not, which is moving faster? How do you (c) Supposing the object is rotating at constant angular speed, are the points Pi and P2 accelerating? If so, are teir (d) Now imagine that the object is speeding up in its rotation (rotating faster and faster with time). Carefully sketch the (e) Of the quantities (velocity, acceleration, distance moved, angular velocity, angular acceleration, angular know? accelerations the same, or not? acceleration vectors for the points Pi and P2 on the diagram. isplacement) which do the points Pi and P2 have in common?
