Why does a nebula spin faster as it contracts?
The reason for faster spin of nebula due to contraction.
Answer to Problem 4RQ
The nebula spins faster on contraction due to conserve the momentum of the nebula.
Explanation of Solution
A nebula is a form of a cloud of gas and dust. The collision occurs between the different particles inside nebula due to strong gravitational pull.
The mass of any nebula remains constant. The nebula shrinks due to the effect of gravity. The gravitational force inside the nebula increases on contraction to gain the spherical shape.
If an object rotates on the shorter circular path, then it rotates faster to conserve momentum of the object. The nebula starts spinning faster on contraction to conserve the momentum of the nebula.
Conclusion:
Therefore, the nebula spins faster on contraction due to conserve the momentum of the nebula.
