What is the relation between torque and angular momentum?
Torque is the rate of change of angular momentum. When a torque is applied to an object, it causes a change in the object's angular momentum. Conversely, an object with angular momentum will require a torque to change its rotational motion.
How can linear momentum be converted to angular momentum?
Linear momentum can be converted to angular momentum through the principle of conservation of angular momentum. When an object with linear momentum moves in a curved path or rotates, its linear momentum can be transferred to create angular momentum. This conversion occurs when there is a change in the object's direction or speed of rotation.
How do you change the speed without changing the angular momentum?
To change the speed without changing the angular momentum, you can change the radius of the rotating object. This is because angular momentum is the product of an object's moment of inertia, its mass, and its angular velocity. By adjusting the radius while keeping the other factors constant, you can alter the speed without affecting the angular momentum.
What is the relationship between the direction of angular momentum and the motion of a rotating object?
The direction of angular momentum is always perpendicular to the axis of rotation of a rotating object. This means that as the object rotates, its angular momentum will also change direction, influencing its motion and stability.
How can one determine the angular momentum of a rotating object and what is the process for finding angular momentum?
To determine the angular momentum of a rotating object, you multiply the object's moment of inertia by its angular velocity. The moment of inertia is a measure of how mass is distributed around the axis of rotation, and the angular velocity is the rate at which the object is rotating. The formula for angular momentum is L I, where L is the angular momentum, I is the moment of inertia, and is the angular velocity.

When the angular speed of an object increase its angular momentum may or may not increase?
if the angular speed of an object increase its angular momentum will also increase
How is torque related to angular momentum and what is the significance of this relationship?
Torque is the force that causes an object to rotate around an axis. Angular momentum is the measure of an object's rotational motion. The relationship between torque and angular momentum is that torque applied to an object will change its angular momentum. This relationship is significant because it explains how forces can affect the rotation of objects, such as in the case of spinning wheels or rotating machinery.
How do you calculate angular momentum in a rotating system?
Angular momentum in a rotating system is calculated by multiplying the moment of inertia of the object by its angular velocity. The formula for angular momentum is L I, where L is the angular momentum, I is the moment of inertia, and is the angular velocity.
What is torque when angular momentum is constant?
When angular momentum is constant, torque is zero. This means that there is no net external force causing the object to rotate or change its rotational motion. The law of conservation of angular momentum states that if no external torque is acting on a system, the total angular momentum of the system remains constant.
What quantities are needed to calculate angular momentum?
"Rate of change" means that you divide something by time ("per unit time" or "per second"), so you would use the units of angular momentum, divided by seconds.I am not aware of any special name for this concept.
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.
What is ment by angular momentum and angular velocity?
Angular velocity means how fast something rotates. The exact definition of angular momentum is a bit more complicated, but it is the rotational equivalent of linear momentum. It is the product of moment of inertia and angular speed.
