Conservation of Angular Momentum AssignmentThis lab is about the conservation of angular momentum. Basically, we have a disc spinning with a certain amount of angular momentum: Li=IiωiLi=Iiωi. We then drop another disc on top of it. The force between the two discs is internal, and does not cause any external torque Thus, the angular momentum along this axis is conserved. The initial angular momentum of the bullet is [latex]mvR[/latex], which is taken about the rotational axis of the disk the moment before the collision. The initial angular momentum of the cylinder is zero. Thus, the net angular momentum of the system is [latex]mvR[/latex] The disc rapidly becomes unstable, as it becomes turbulent, but in the process angular momentum is redistributed from the inner portion of the disc to the outer. Simulations, such as those shown in figure 2 , illustrate the growth of the instability within a relatively small number of disc rotation timescales A uniform solid disk of mass m = 2.94 kg and radius r = 0.200 m rotates about a xed axis perpendicular to its face with angular frequency 6.02 rad/s. • a)Calculate the magnitude of the angular momentum of the disk when the axis of rotation passes through its center of mass. • b)What is the magnitude of the angular momentum when th Checkpoint: Angular Momentum Deadline: 10096 until Wednesday, November 12 at 9:00 AM Block on Spinning Disk la Top View The angular momentum of a freely rotating disk around its center is Ldisk.

A digital sensor is connected to the axle so that students may measure the angular speed of the disk as it rotates. Students may vary the angular speed of the disk-axle apparatus as data is collected. Students want to plot the magnitude of the angular momentum of the disk as a function of time for a known time interval Δt0 Start it spinning and watch the law of conservation of momentum run its course. As friction begins to slow its spin, the disk tips over and rotates in a flatter orientation, which increases its moment of inertia, allowing for angular momentum to be conserved even with a reduced rate of rotation Conservation of Angular Momentum.

Such a system might represent a true multi-component system, such as an asteroid cloud, or it might represent an extended body. Let the th particle, whose mass is , be located at vector displacement (d) She decreases her moment of inertia, thus decreasing her angular speed. (e) Her angular speed remains constant by conservation of angular momentum. The moment of inertia I is proportional to R 2; hence, if her weighted value of R 2 increases, so does I.

The angular momentum of rotation is approximately 10 42 kg.m2.s-1 and the angular momentum of revolution is about 3x10 43 kg.m2.s-1, i.e. 30 times. Then there is a paradox because the planets are only 1% of the total mass of the solar system should have only a small part of the angular momentum of the Sun, while it represents 97% of the total. If angular momentum transport within the disk is important, disks will spread with time as the fraction of the disk that takes up the excess angular momentum moves to larger radii and the remainder accretes (Lynden-Bell & Pringle 1974; Hartmann et al. 1998). If disk winds remove the excess angular momentum, disks need not grow in size with time This decrease in angular momentum of the small disk should decrease the angular momentum of the big wheel. The reverse is true also. If the big wheel starts spinning and the small disk is turned.
