Distances/Angular momenta/Quiz

Angular momentum is a lecture from the radiation astronomy department about a classical topic of Newtonian kinetics.

You are free to take this quiz based on angular momenta at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, External links, and in the template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Suggestion: Have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!

Quiz
{Yes or No, When swinging a baseball bat, the end of the bat farthest away from the swinger has angular momentum. + Yes - No
 * type=""}

{What effect does the distribution of angular momentum in the solar system have on the origin of the Sun? - an initially spherical and contracting nebula spinning faster as it collapses would produce the present situation in the solar system + partitioning mass and angular momentum does not seem possible with a contracting nebula + the rotation axis of the Sun from that of the system as a whole if formed by nebular collapse seems very unlikely + the angular-momentum problem does not arise with the accretion theory - surface differential rotation of the Sun results + by the nature of the floccule process the star so formed will have little angular momentum
 * type="[]"}

{True or False, The differential profile of the Sun's surface extends into the solar interior as rotating cylinders of constant angular momentum. - TRUE + FALSE
 * type=""}

{Which of the following are involved in kinetics? + a quantity cohering together so as to make one body, or an aggregation of particles or things which collectively make one body or quantity - objects in motion, but not with the forces involved + every body persists in its state of being at rest or of moving uniformly straight forward, except insofar as it is compelled to change its state by force impressed + the product of a body's mass and velocity + the rotary inertia of a system such as an isolated rigid body is a measure of the extent to which an object will continue to rotate in the absence of an applied torque + a turning effect of a force applied to a rotational system at a distance from the axis of rotation
 * type="[]"}

{True or False, Any conversion of mechanical energy into electrical energy and associated magnetic fields is a dynamo. + TRUE - FALSE
 * type=""}

{True or False, Star fission may be the splitting of a star at a critical angular momentum. + TRUE - FALSE
 * type=""}

{Yes or No, A relationship exists between force (F), torque (τ), momentum (p), and angular momentum (L) vectors in a rotating system. + Yes - No
 * type=""}

{True or False, A rotational or twisting effect of a force is called a torque. + TRUE - FALSE
 * type=""}

{Yes or No, A radius vector consists of two parts or concepts: a distance, or displacement, and a direction, indicated by the arrow. + Yes - No
 * type=""}

{True or False, In a closed system, no torque can be exerted on any matter without the exertion on some other matter of an equal and opposite torque. + TRUE - FALSE
 * type=""}

Hypotheses

 * 1) Angular momenta can be created, enhance, countered or eliminated by charge distributions.
