Question

Stars originate as large bodies of slowly rotating gas. Because of gravity, these clumps of gas slowly decrease in size. The angular velocity of a star increases as it shrinks because of

Definition Definition Rate of change of angular displacement. Angular velocity indicates how fast an object is rotating. It is a vector quantity and has both magnitude and direction. The magnitude of angular velocity is represented by the length of the vector and the direction of angular velocity is represented by the right-hand thumb rule. It is generally represented by ω.

A star that has the same mass and radius as the Sun rotates at an angular velocity 1.2 revolutions per month. The star collapses into a white dwarf that has a radius of 3.0 km. What is its angular velocity after the collapse?
A supergiant star collapses during a supernova blowing off 80.080.0% of it's mass. Angular momentum of the remaining star mass is conserved during the mass blow-off, and so the star spins rapidly. If the initial star diameter is 1.951.95 million kilometers, and it collapses to 14.014.0 km, find the resulting angular velocity in radians per second, given the star's initial angular velocity was 1.01.0 revolution per 36.036.0 days.

Our sun rotates around its axis once every 27 days. What is the sun’s angular velocity in rad/s? What is the sun's moment of inertia in kg*m2? (Assume it’s a solid sphere) If the sun turned into a red giant, the radius would increase to 100 times its current radius.

A star with a of mass of 3.0x1032 kg and radius 7.0x108 m is initially rotating at a rate of once every 30 days. The star collapses into a neutron star with the same mass but a new radius of 18,000 m. What is the new angular speed of the star? (Give your answer in rotations per second.) Assume the star is a solid sphere: Isphere = 2/5 MR2.
Under some circumstances, a star can collapse into an extremely dense object made mostly of neutrons and called a neutron star. The density of a neutron star is roughly 1014 times as great as that of ordinary solid matter. Suppose we represent the star as a uniform, solid, rigid sphere, both before and after the collapse. The star’s initial radius was 7.0 * 105 km, its final radius is 16 km. If the original star rotated once in 30 days, find the angular speed of the neutron star.
