The Rules Of The Solar System and The Galaxy

Solar Nebula Theory- The solar nebula theory states that the solar system came to be when a star exploded and formed a rotating nebula that from which the sun and planets were formed.

• Newton’s Three Laws-

1)The law of inertia-An object at rest will stay at rest and an object in motion will stay in motion until acted upon by an unbalanced force

2)F=ma

3)Every action has an equal and opposite reaction

• Kepler’s Three Laws-

1)The Law of Ellipses-Planets orbit the sun in an ellipse

2)The Law of equal areas-speed at which any planet moves through space is constantly changing. A planet moves faster when it is closer to the sun

3)The Law of Harmonies-compares the orbital period and radius of orbit of a planet to those of other planets. Orbital period squared over the average distance from the sun cubed is the same for every planet

• How Fast you are moving when you are sitting still

Universe-stretches-gamma-rays expand to x-rays to ultra-violet light to visible light to micro and radio waves.

Galaxy-spinning- thought to be orbiting the universe and moving through space towards The Great Attractor at 1.3 million miles per hour

Sun and therefore the solar system- milling around or orbiting the center of the galaxy at 483000 miles per hour. 225 million years per orbit

Earth-spinning at 1000 miles per hours and revolving around the sun at 66000 miles per hour

Explain the rules that govern or solar system and galaxy
