The interstellar cloud that formed our solar system rotated more rapidly as it collapsed due to the law of conservation of
A) energy
B) mass
C) volume
D) angular momentum

Question

Quizplus · Accepted Answer

The law of conservation of angular momentum states that the total angular momentum of a system remains constant unless an external torque is applied. As the interstellar cloud collapsed, it had to conserve its angular momentum, and therefore it began to rotate faster and faster as it became smaller and smaller.
