Conservation of angular momentum
3
Q
How does a solar nebula get hot?
A
collapse - conservation of energy
4
Q
how does a solar nebula turn into a disk?
A
collisions force common motions - conservation of momentum
5
Q

A
directions of things that hit each other average out, different speeds of things average out as well.
