What happens when a spinning ice skater draws in her outstretched arms group of answer choices?

Question: What Happens When A Spinning Ice Skater Draws In Her Outstretched Arms? Her Angular Momentum Increases. Her Moment Of Inertia Decreases Causing Her To Speed Up. Her Moment Of Inertia Decreases Causing Her To Slow Down.

Why can an ice skater increase their angular velocity during a spin without and external force or torque?

Angular Momentum in Figure Skating According to the law of the conservation of angular momentum, the angular momentum of an object will not change unless external torque is applied to the object. So, in order to spin/jump, the skater must generate angular momentum.

How does torque affect angular velocity?

An object that is rotating at constant angular velocity will remain rotating unless it is acted upon by an external torque. The larger the torque, the larger the angular acceleration.

Does increasing torque increase angular momentum?

1 Answer. A torque causes angular momentum to decrease, increase or change direction.

Is torque in the same direction as angular momentum?

Torque is perpendicular to the plane formed by r and F and is the direction your right thumb would point if you curled the fingers of your right hand in the direction of F. The direction of the torque is thus the same as that of the angular momentum it produces.

Is angular momentum conserved if there is friction?

The angular momentum of each disk individually is not conserved, however the total angular momentum of both disks is conserved because there are no external torques acting. There are internal forces, namely in this case, friction, but that doesn’t matter.

Does friction increase torque?

The torque can be affected by an opposing force that results from a resistant surface. The frictional torque, therefore, is calculated as the difference between the applied torque and the resulting net, or observed, torque.

Is torque a friction?

Friction torque is the torque caused by the frictional force that occurs when two objects in contact move. Like all torques, it is a rotational force which may be measured in newton metres or pounds-feet.
