Thus, the angular momentum depends on the mass, velocity, and radius.
What does angular momentum depend on quizlet?
Angular momentum depends on mass, speed, and radius. Acceleration toward the center of a circular path. A force directed toward the center of a circle that keeps an object moving in a circular path.
What are the quantities needed to find calculate the angular momentum?
With a bit of a simplification, angular momentum (L) is defined as the distance of the object from a rotation axis multiplied by the linear momentum: L = r*p or L = mvr.
Which quantity is angular momentum?
The Earth has orbital angular momentum by reason of its annual revolution about the Sun and spin angular momentum because of its daily rotation about its axis. Angular momentum is a vector quantity, requiring the specification of both a magnitude and a direction for its complete description.
What is the most influential factor of angular momentum?
Angular momentum depends on two quantities, moment of inertia and angular velocity.
Why did solar nebula heat up as it collapses?
3) Why did the solar nebula heat up as it collapsed? A) Nuclear fusion occurring in the core of the protosun produced energy that heated the nebula. … As the cloud shrank, its gravitational potential energy was converted to kinetic energy and then into thermal energy.
What is the definition of angular momentum in physics?
: a vector quantity that is a measure of the rotational momentum of a rotating body or system, that is equal in classical physics to the product of the angular velocity of the body or system and its moment of inertia with respect to the rotation axis, and that is directed along the rotation axis.
Is angular momentum always conserved?
Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero.
What is the symbol of angular momentum?
What is the formula for orbital angular momentum?
The total orbital angular momentum is the sum of the orbital angular momenta from each of the electrons; it has magnitude Square root of√L(L + 1) (“), in which L is an integer.
Is angular momentum constant?
Just like how linear momentum is constant when there’s no net force, angular momentum is constant where there’s no net torque.
What is angular momentum example?
Another popular example of the conservation of angular momentum is that of a person holding a spinning bicycle wheel on a rotating chair. The person then turns over the bicycle wheel, causing it to rotate in an opposite direction, as shown below.
What is angular momentum in simple words?
Angular momentum is defined as: The property of any rotating object given by moment of inertia times angular velocity. It is the property of a rotating body given by the product of the moment of inertia and the angular velocity of the rotating object.
Why is angular momentum conserved?
Her angular momentum is conserved because the net torque on her is negligibly small. In the next image, her rate of spin increases greatly when she pulls in her arms, decreasing her moment of inertia. The work she does to pull in her arms results in an increase in rotational kinetic energy.
Why is angular momentum important?
The concept of angular momentum is important in physics because it is a conserved quantity: a system’s angular momentum stays constant unless an external torque acts on it. … The conservation of angular momentum explains many phenomena in human activities and nature.
What is the angular momentum of Earth?
Compared with the orbital angular momentum, the Earth’s spin angular momentum is negligible. So the total angular momentum of the Earth about the Sun is approximately 2.7 × 1040 kg m2 s‘1.
