Science Class Weeek of 1/18/10


Hei kieba Sup peeps? Kupo! (idk y but I feel like writting in piiink!!! XD)


Mon: OFF!!! MWAHAHASHHAHAHHA!!!! YEAH!!!! Happy B-day Martin Luther King Jr.!!!! Kupo! XD


Tues: Lesson yup... Kupo!


Wed: Alriiiighhtttyyyy then here's what we did kupo!


Soooo the Earth pulls on the moon directly to its center kupo. And we tried to think of why the moon wouldn't crash into the Earth kupo. We watched a video of a guy smashing a bowling ball with a hammer in a circle kupo. He was Balancing the force of the bowling ball out kupo!


Thurs: We had to do a simulation on the Earth not crashing into the sun kupo!


Fri: Notes on yesterday's simulation kupo:


Object or satellite has to be in motion (initial velocity)kupo


Too small of a motion and it will crash kupo


Too large and it "Flys away" kupo


"An escape velocity" kupo


Distance affects the amount of initial velocity necessary to put it into motion. Kupo


Faraway neeeds aliitle kupo


Closer neeeds alot kupo


Needs 2 objects kupo


Perpendicular velocity kupo


Then we thought if the Sun suddenly disappeared the planet would fly away in a straight line kupo. We tested this with wood circle and spun a ball in the centerkupo. Then we took away a piece and the ball went in a straight line like it originally "wanted to". kupo




Thats it KUPO!!!


yup XD kupo!
