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...

Determine the moment of inertia of a uniform cube when the rotation axis is along an edge. Suppose its total mass is M=2.5kg, the edges are each 10.0 cm long, it begins at rest, and a constant force, F=4.0N is applied to the edge diagonally opposite the rotation axis. The moment arm and the force are at an angle of 60 degrees. What would its angular displacement from the start be when its angular velocity is 13 rad/s? Draw the...

A 75.0 kg astronaut is training for accelerations that he will experience upon reentry. He is placed in a centrifuge (r = 20.0 m) and spun at a constant angular velocity of 15.0 rpm (revolutions per minute). He is then slowed and brought to a stop in 2.0 minutes. a. Find the magnitude and direction of the centripetal acceleration and force when he is spinning at constant angular velocity. b. How many g’s is the astronaut experiencing when moving at...

P 6 A student stands on a freely rotating platform while holding a 3.00kg mass in each hand. With arms fully extended the masses are 1m from the axis of rotation and the student rotates with an angular speed of 0.750rad/s. The moment of inertia of student plus platform is 3kg.m2 and does not change much as they bring their arms in or move them out because most of their mass is...

Lab 8 Assignment: Moment of Inertia 1) Moment of Inertia for Different Systems The resistance to rotational motion change is more involved than for linear motion because it not only depends on what the mass is, but also on how that mass is distributed about the axis of rotation. The farther away from the axis the mass is distributed, the greater the moment of inertia. Using this simple definition, for each of the following pairs of objects, determine which of...
