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

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.


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.


What quanties are needed to calculate angular momentum?

To calculate angular momentum, you need the object's moment of inertia, its angular velocity, and the axis of rotation. The formula for angular momentum is given by L = I * ω, where L is the angular momentum, I is the moment of inertia, and ω is the angular velocity.


Does the moment of inertia give an object's resistance to changes in angular velocity?

Moment of inertia is a property of a rotating body that defines its resistanceto a change in angular velocity about an axis of rotation.===========================By carefully reading and analyzing the treatment above, we arelead to infer that the actual answer to the question is 'yes'.


Why is angular momentum of a body is equal to the product of its moment of inertia and angular velocity?

Angular momentum about the axis of rotation is the moment of linear momentum about the axis. Linear momentum is mv ie product of mass and linear velocity. To get the moment of momentum we multiply mv by r, r the radius vector ie the distance right from the point to the momentum vector. So angular momentum = mv x r But we know v = rw, so angular momentum L = mr2 x w (w-angular velocity) mr2 is nothing but the moment of inertia of the moving body about the axis of rotation. Hence L = I w.

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.


How angular momentum is equals to kgms?

Angular momentum is calculated as the product of a rotating object's moment of inertia (I) and its angular velocity (ω). The units of angular momentum are kg m^2/s, which is the same as the units for moment of inertia multiplied by angular velocity (kg m^2 * 1/s). This relationship is based on the principles of rotational motion and conservation of angular momentum.


How does the skater decrease his moment of inertia and increase his angular velocity?

The skater can decrease his moment of inertia by bringing his limbs closer to his body, which decreases the distribution of mass. To increase his angular velocity, the skater can generate more angular momentum by pushing off the ice with greater force, allowing for a faster spin.


What structure is involved in angular acceleration?

Angular acceleration is a measure of how quickly the angular velocity of an object is changing. It involves the object's moment of inertia and the net torque acting on it. When a torque is applied to an object with a certain moment of inertia, it causes the object to accelerate rotationally.


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 is the torque acceleration equation used to calculate the rate of change of angular velocity in a rotating system?

The torque acceleration equation is used to calculate the rate of change of angular velocity in a rotating system. It is given by the formula: Torque Moment of Inertia x Angular Acceleration. This equation relates the torque applied to an object to its moment of inertia and the resulting angular acceleration.


Why moment of inertia is also called rotational inertia?

Because it is a measure of the "resistence" of an object to be accelerated in its rotation. An object with a big moment of inertia is more difficult to increase/decrease its angular velocity (speed of rotation), than an object with a low moment of inertia.
