Explain the difference between Dark Energy and Dark Matter.
Explain the difference between Dark Energy and Dark Matter.
Dark Energy is a hypothesized energy that is responsible for the universe's expansion, while Dark Matter is a hypothesized mass that explains faster rotating galaxies.
Describe the stages involved in the life cycle of a star.
Describe the stages involved in the life cycle of a star.
The stages involved in the life cycle of a star include protostar, main sequence, red giant/ supergiant, planetary nebula, and white dwarf/ black hole/ neutron star.
How does gravity maintain circular orbits?
How does gravity maintain circular orbits?
Gravity maintains circular orbits by exerting a force that pulls objects towards the center of the orbit, balancing the centrifugal force that pushes objects away from the center.
