Life Cycle of a Star | GCSE Physics Practice
Stars lifecycle depends on their initial mass, from formation in a nebula to their final end.
What is the next stage for a star the size of our Sun after the Main Sequence?
What is Life Cycle of a Star | Practice?
"The evolutionary path of a star determined by its initial mass, spanning from formation to final remnant."
Star Stages
Formation: Dust and gas (nebula) pulled together by gravity.
Main Sequence: Stable period where radiation pressure balances gravity.
Sun-sized: Red Giant -> White Dwarf -> Black Dwarf.
Massive stars: Red Super Giant -> Supernova -> Neutron Star or Black Hole.
Key Balance: A star stays stable (Main Sequence) because the outward pressure from fusion exactly balances the inward pull of gravity.

The fastest way to improve your grade is to practise exam-style questions, identify your gaps, and focus only on what you don't know.
