Why does an object go faster as it gets closer to its star?
We drew the planets to the sun on the paper.
The planet that is the closest to the sun would be the fastest moving. The farer away the slower they move because they sun is pulling it to move. It goes faster because it has a gravitational pull that is pulling it to the star.
All of the planets move in a elliptical orbit with the sun at one force
How do stars produce elements?
Nuclear Fusion- a Nucl nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy
We had to draw the sun and the stars.
The rocky planets are the first four and the gases are the last 4 and pluto is a rocky planet. If the mass of the sun would get bigger or smaller the earth would run right into the suns and all the planets would go all over the place.
The leftover rockys and leftover things from when they big bang happened.
What evidence is there for the Big Bang.
Is a star that is fusing hydrogen into helium in its core and it has a stable balance. Brightness is when you are saying how bright the star appears on the outside. Luminosity is the amount of light on the surface of the star.
Redshift- the light from that galaxy gets closer to Earth and as we get father away from planets the wavelengths get bigger.
CMS- early universe was a very hot place and that as it expands the gas within it cools
If the planets get farer away there galaxies don’t move just the planets just get bigger. We are in an orbit because after the bang happened we started to spin and that is why we are in a orbit. We stay in our orbit because of gravity.
The cosmic microwave background. Is leftover radiation from the big bang.
