What factors does the angular momentum depend upon?
Angular momentum depends on the mass of an object and its rotational speed. The greater the mass or speed, the greater the angular momentum.
When is the angular momentum of a system not conserved?
The angular momentum of a system is not conserved when external torques are applied to the system. These torques can change the angular momentum by causing the system to rotate faster or slower or by changing the direction of its rotation.
What is the angular momentum of the ice skater spinning with her arms out and not being acted upon by an external torque?
The angular momentum of the ice skater spinning with her arms out and not being acted upon by an external torque remains constant.
In orbital motion the Angular Momentum of the system is?
In orbital motion, the angular momentum of the system is constant if there is no external torque acting on the system. This is a result of the conservation of angular momentum, where the product of the rotating body's moment of inertia and angular velocity remains constant unless acted upon by an external torque.
What is the law of inertia for rotating systems in terms of angular momentum?
The law of inertia for rotating systems in terms of angular momentum states that an object will maintain its angular momentum unless acted upon by an external torque. This is a rotational equivalent of Newton's first law of motion, which states that an object in motion will stay in motion unless acted upon by an external force.
What is the best example that demonstrates the conservation of angular momentum?
One of the best examples that demonstrates the conservation of angular momentum is the spinning ice skater. When a skater pulls in their arms while spinning, their rotational speed increases due to the conservation of angular momentum. This principle shows that the total angular momentum of a system remains constant unless acted upon by an external torque.
If something shrinks in size but not in mass what happens to its angular momentum?
Angular momentum is maintained in such a case - and in fact in all cases, unless angular momentum is transferred to, or from, another body. This means it must rotate faster.Angular momentum is maintained in such a case - and in fact in all cases, unless angular momentum is transferred to, or from, another body.

Angular momentum about the center of the planet is conserved?
Angular momentum is conserved when there is no external torque acting on a system. For a planet, the net torque acting on it is negligible, so its angular momentum about its center will be conserved unless acted upon by an external force. This conservation principle is a consequence of the rotational symmetry of the system.
What is the difference between linear momentum and angular momentum, and how does this difference impact the motion of objects?
Linear momentum is the momentum of an object moving in a straight line, while angular momentum is the momentum of an object rotating around an axis. The main difference is the direction of motion - linear momentum is in a straight line, while angular momentum is in a circular motion. This difference impacts the motion of objects by determining how they move and interact with their surroundings. Objects with linear momentum will continue moving in a straight line unless acted upon by an external force, while objects with angular momentum will continue rotating unless a torque is applied to change their direction.
The product of an object's rotational inertia and its rotational velocity is?
The product of an object's rotational inertia and its rotational velocity is called angular momentum. It is a conserved quantity in a closed system, meaning it remains constant unless acted upon by an external torque.
What does the earth spins on?
the earth spins on an axis, which is carried over by conservation of angular momentum when the earth was created
Why does a skater spin faster when she pulls her arms in toward her body?
When a skater pulls her arms in towards her body, she reduces her moment of inertia, which is the resistance to changes in rotation. This causes her to spin faster due to the conservation of angular momentum, which states that angular momentum must remain constant unless acted upon by an external torque. By bringing her arms closer to her body, she decreases her moment of inertia, causing her angular velocity (spin speed) to increase to maintain constant angular momentum.
