This week, we learned more about centripital force and now how it affects planets. We learned how the planets orbit around the sun and how our moon also orbits the sun but gets pulled back by the earth. The movement of the planets is just like how things on earth move in a circle on earth.
I know that centripital force is when somethings acceleration is going towards the center of the circle but their inertia wants them to travel tangent to the circle. This is why you get the circular pattern. This is because it is now traveling in between those to directions.
The same kind of thing is happening to the planets right now. As we orbit around the sun, we are being pulled in by it, but are inertia wants it to travel tangential to the orbit. The moons orbit is a little weird because it is orbiting around the sun but it also gets pulled by the earth. So it resembles a car that is constantly trying to pass another car.
We looked at a demonstration of the planets and the moons motion on the computer. That demonstration really helped me learn what the orbit looked like. I believe that I get all thats being taught right now so I don't have any questions yet.
