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...

Calculate the angular momentum for a rotating disk, sphere, and rod. (a) A uniform disk of mass 16 kg, thickness 0.5 m, and radius 0.9 m is located at the origin, oriented with its axis along the y axis. It rotates clockwise around its axis when viewed from above (that is, you stand at a point on the +y axis and look toward the origin at the disk). The disk makes one complete rotation every 0.7 s. What is the...
