Frequently Asked Questions
What is the life cycle of a star like the Sun?
Nebula → Protostar → Main sequence star → Red giant → White dwarf. For massive stars: ... → Red supergiant → Supernova → Neutron star or Black hole.
What is red-shift GCSE Physics?
Light from distant galaxies is shifted towards the red end of the spectrum because galaxies are moving away from us. The further away, the greater the red-shift, supporting the expanding universe theory.
What causes circular orbital motion?
Gravity provides the centripetal force needed for orbital motion. The velocity is perpendicular to the force. Objects in stable orbits have constant speed but changing velocity (direction changes).
Is Space Physics Triple Science only?
Yes! The entire Space Physics topic is Triple Science only. Combined Science students do NOT need to learn this topic.
