If a particle moves in circle with constant speed its angular momentum about the center of circle?
The angular momentum is a constant.
What is the angular momentum of the 2.6 kg 5.6 cm diameter rotating disk.?
Without knowing the angular speed, i.e. RPM or some such velocity, it is not possible to answer the question. Please restate the question, giving all of the required information.
What keeps a spinner spinning?

angular momentum
What is Planck's constant dimensionally equal to?
Planck's Constant is dimensionally equal to Angular Momentum. The unit is Joules second.
Do all rotating objects have angular momentum?
Rotating objects all have angular momentum.
Is angular momentum a vector quantity?
Yes, angular momentum is a vector quantity. It has both magnitude and direction, with the direction given by the right-hand rule for rotating systems.
What is anguler momentum?
Angular momentum is a property of a rotating object that describes its tendency to keep rotating. It is calculated as the product of an object's moment of inertia and its angular velocity. Similar to linear momentum, angular momentum is conserved in the absence of external torques.
What is the direction of angular momentum?
Angular momentum is a vector quantity, which means it has both magnitude and direction. The direction of angular momentum is perpendicular to the plane in which the object is rotating, following the right-hand rule. It points along the axis of rotation, with a direction given by the direction in which a right-hand screw would move if turned in the same way as the object's rotation.
Why is the law of inertia for rotating system in terms of angular momentum?
The law of inertia for rotating systems is described in terms of angular momentum because angular momentum is conserved in the absence of external torques, similar to how linear momentum is conserved in the absence of external forces according to Newton's first law. This conservation of angular momentum provides a useful way to analyze and understand the motion of rotating systems.
When the rotational speed of a rotating system doubles its angular momentum?
When the rotational speed of a rotating system doubles, its angular momentum also doubles. This is because angular momentum is directly proportional to both the mass and the rotational speed of the system. Therefore, if the rotational speed doubles, the angular momentum will also double.
How a body can have angular momentum when it is moving in straight line?
A body can have angular momentum when moving in a straight line if it is rotating about a different axis or point. The angular momentum is a measure of the body's rotational motion and is independent of its linear motion. So, even if the body is moving straight, the angular momentum can still be present due to its rotation.
If you generate more angular momentum you have the potential to spin faster true or false?
True. Angular momentum is a measure of how fast something is rotating. By increasing the angular momentum, you can increase the rate at which an object spins.
Is the direction of angular velocity same as that of angular momentum when agular velocity is decreasing?
No, the direction of angular velocity and angular momentum are not always the same. Angular momentum is defined as the cross product of the position vector and linear momentum, so the direction of angular momentum depends on both the direction of linear momentum and the position vector. Therefore, when angular velocity is decreasing, the direction of angular momentum may change depending on the specific conditions of the system.
What is angular momentum?
Angular momentum is a measure of an object's rotational motion, determined by the mass of the object, its angular velocity (rate of rotation), and the distribution of mass around its axis of rotation. It is a vector quantity, with both magnitude and direction, and is conserved in the absence of external torques.
What has angular momentum?
Angular momentum is a property that objects possess when they are rotating around an axis. It is defined as the product of an object's moment of inertia and its angular velocity. It plays a crucial role in various scientific fields, including physics and engineering.
What is the difference between angular velocity and angular momentum?
Angular velocity is a measure of how fast an object is rotating around a specific axis, usually measured in radians per second. Angular momentum, on the other hand, is a measure of how difficult it is to stop an object's rotation, calculated as the product of angular velocity and moment of inertia. In simple terms, angular velocity is the speed of rotation, while angular momentum is the rotational equivalent of linear momentum.
