In the proto-solar system nebula, gravity pulled matter together to form larger bodies. As they collided, what happened to these bodies?
◦ Oblique collisions caused individual bodies to spin.
◦ The objects temporarily broke apart and then reformed into large objects, cooling rapidly during the breakup period.
◦ Immense heat was released within the colliding bodies as gravitational potential energy was converted to heat.
◦ The objects broke apart to form asteroids, much like a neutron colliding with a heavy atom produces fission.
