What theoretical concept describes the minimum mass a cloud fragment needs to overcome internal pressure and begin gravitational contraction?

Answer

Jeans Mass

The Jeans Mass represents the critical threshold where the self-gravity of a cloud fragment becomes strong enough relative to its temperature and density to initiate runaway collapse.
