1. Use the sentences to answer the question.
Comets often have orbits that take them far from the sun, where they move very slowly in their orbit. As they come closer in toward the sun, their orbital speed increases quite a bit.
Which statement correctly describes the angular momentum of a comet during its orbit?
A. The angular momentum will be the same throughout the orbit around the sun.
B. The angular momentum is greatest when the comet is farthest from the sun.
C. The angular momentum is greatest when the comet is closest to the sun.
D. The angular momentum will be the same as the sun's angular momentum.
2. How is angular momentum calculated?
A. It is the product of the mass, tangential velocity, and orbital radius of an object.
B. It is equal to the product of mass and tangential velocity divided by the orbital radius.
C. It is the product of the tangential velocity and orbital radius divided by the mass.
D. It is equal to the product of the mass and orbital radius divided by the tangential velocity.
1. B. The angular momentum is greatest when the comet is farthest from the sun.
2. A. It is the product of the mass, tangential velocity, and orbital radius of an object.
