Question

What is the source of energy for a contracting protostar? Please help.

Answer 1

Gravity it is. Potential energy becoming kinetic energy and forcing the pressure and temperature up until it gets hot and dense enough for a fusion reaction to start taking place.

Answer 2

learn up on the suited gas equation The protostar solar replace into overwhelmed by utilising potential of it particularly is amazingly very own gravity, reducing it particularly is quantity and as a consequence increasing it particularly is temperature. This enhance in temperature even although factors kinetic skill to the atoms indoors the solar allowing them to rigidity the solar to spice up and as a consequence cool. This cycle will repeat lower back and lower back decrease lower back till the vast call settles, a good value of fusion is maintained and an equilibrium is met between the forces controlling it particularly is length.

Answer 3

I would say gravity is. Once enough matter collects in one place and gets compressed enough by gravity, fusion begins. Gases get hot when you compress them, that's how the outdoor unit of your air conditioner works.

Answer 4

Yeah..Gravity.
