Learning Goal: To learn the definition andapplications of angular momentum including its relationship totorque. By now, you should be familiar with the concept ofmomentum, defined as the product of an object's mass andits velocity: . You may have noticed that nearly every translationalconcept or equation seems to have an analogous rotationalone. So, what might be the rotational analogue of momentum? Just as the rotational analogue of force , called thetorque , isdefined by the formula , the rotational analogue of...

1) The flywheel of a steam engine begins to rotate from rest with a constant angular acceleration of 1.23 rad/s2. It accelerates for 22.7 s, then maintains a constant angular velocity. Calculate the total angle through which the wheel has turned 57.7 s after it begins rotating. Hint:This is rotational motion, with equations for angles similar to those for linear motion. Note that the TOTAL time is given. Answer: ______ deg. 2) A proposed space station includes living quarters in...
