A star forms when a molecular cloud collapses under its own gravity forming a dense core sustained by nuclear fusion. This happens only when the force of gravity pulling in exceeds the outward push of pressure. High-density molecular clouds have stronger forces of gravity pulling in, making it easier to overcome the total pressure within the cloud. Once started, the collapse of the solar nebula continues on its own. Use the law of gravitational attraction to explain this phenomenon.
Once started, this the collapse of the solar nebula continues on its own. Use the law of gravitational attraction to explain this phenomenon.
A) As the cloud shrinks in size the mass decreases and the gravitational attraction increases. Gravity is indirectly related to mass.
B) There is a direct correlation between kinetic energy and gravitational attraction. The more the mass rotates, the greater the attractive force.
C) The force of gravity exerted on the cloud grows stronger as the cloud shrinks in size. Gravitational attraction increases as distance decreases.
D) The force of gravity continues to grow as the temperature of the solar nebula increases. Gravitational attraction increases with higher temperatures.
