| Term | Definition |
|---|---|
| first law | planets move in elliptical order |
| second law | object in space moves fast when closer to the sun |
| third law | planets closer to the sun will have a shorter orbital period |
| close to 1 | more elliptical |
| close to 0 | perfect circle |
| what shape are planets orbits | planets orbits are ellipses like earth |
| what happens to the gravitational force when its far from the sun | further away from sun= gravitational force weaker |
| aphelion | far from sun in its orbit |
| perihelion | close to sun in its orbit |
| what happens to the force of object when they increase | force of gravity decreases as distance between 2 objects increase |
| cause of tides | moon and suns gravitational pull and the moon has more of an affect bc its closer |
| effect of distance | moon further= weaker tides b/c gravitational pull would decrease |
| perihelion&aphelion (1) VS. perigee&aphelion (2) | 1 planets orbiting around the Sun & 2 moon orbiting around Earth |
| why are we in winter even tho its perihelion | its perihelion because the Earth is tilted away from the sun. |
