Gravity
An attraction between 2 masses (objects).
Force of gravity formula
F=G (m1)(m2)/(r)² f= force of gravity, g= gravitational constant m=mass, r=radius distance
Light
Formed from big bang
Heavy
Formed from inside stars doing fusion
1 Billion years after expansion
Galaxy and planets were formed due to gravity
Fusion and benefits for us
Process combines atoms, releasing energy in the form of heat and light, which is used to generate power
Life cycle of our star (sun)
The Sun forms from a gas cloud, shines as a star, grows into a red giant, and then shrinks into a white dwarf
Life path of larger stars
Turn into supergiants, explode as supernovae, and become black holes
