Angular momentum is a measure of?
angular momentum is the measure of angular motion in a body.
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
What equations link angular and linear momentum If you exert a force on a free floating body it will have angular and linear momentum In what proportions and how are they linked?
angular momentum = linear momentum (of object) x perpendicular distance (from origin to the object) where x stands for cross product. angular momentum = mv x r (perpendicular dist.)
Is angular momentum always parallel to angular acceleration?
momentum is product of moment of inertia and angular velocity. There is always a 90 degree phase difference between velocity and acceleration vector in circular motion therefore angular momentum and acceleration can never be parallel
What feature of an orbital is related to the angular momentum quantum number l?
An atomic orbital is a mathematical term signifying the characteristics of the 'orbit' or cloud created by movement of an electron or pair of electrons within an atom. Angular momentum, signified as l, defines the angular momentum of the orbital's path as opposed to values n and m which correspond with the orbital's energy and angular direction, respectively.
What is the SI units torque and angular momentum?
The SI unit for torque is the newton-meter (N-m). The SI unit for angular momentum is kilogram square meter per second (kg.m^2/s).
Angular momentum is a measure of?
angular momentum is the measure of angular motion in a body.
What is ment by angular momentum and angular velocity?
Angular momentum is a measure of an object's rotational motion, calculated as the product of its moment of inertia and angular velocity. Angular velocity, on the other hand, is the rate of change of angular displacement of an object rotating around an axis. It is measured in radians per unit time.
What quantities are needed to calculate angular momentum?
To calculate angular momentum, you need the object's moment of inertia (a measure of its mass distribution), its rotational velocity, and the object's shape. The formula for angular momentum is L = IΟ, where L is the angular momentum, I is the moment of inertia, and Ο is the angular velocity.
Why is angular momentum NOT measured in kg m2 rad s-1?
Angular momentum is not measured in kg m^2 rad s^-1 because the unit for angular momentum is kg m^2 s^-1 or N m s (newton meter-second). This unit is derived from the definition of angular momentum as the product of a moment of inertia (kg m^2) and angular velocity (rad s^-1), without including the radian unit.
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 * Ο, where L is the angular momentum, I is the moment of inertia, and Ο is the angular velocity.
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.
Which component of linear momentum does not contribute to angular momentum?
The linear momentum component that does not contribute to angular momentum is the component that is parallel to the axis of rotation. Only the perpendicular component of linear momentum contributes to angular momentum.
How do solve conservation of angular momentum?
To solve for conservation of angular momentum, set the initial angular momentum equal to the final angular momentum. This means that the total angular momentum before an event is equal to the total angular momentum after the event, assuming no external torques act on the system. This principle is commonly used in physics to analyze rotational motion.
How angular momentum of the earth remain constant?
As there is no external torque acting on it, its angular momentum remains constant. This is according to the law of conservation of angular momentum
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.
Do all rotating objects have angular momentum?
Rotating objects all have angular momentum.
