Science Help Center
Need some help with science homework? Then you've come to the right place. ^_^ This place is designed for those in elementary (middle) and high school who need help with science homework. I'm done my second year of university (studying astrophysics) now, so I'm really good at science and math and I'll do my best to help.
Please note that I'm not here to do your homework for you. I'll do my best to help you understand how to solve the problem or answer any questions you have or explain stuff to you. Also please don't complain if I can't help. I'm doing my best here.
Also, I'm especially good at physics, but know hardly anything about bio. If you have a biology related question I'm probably not going to be able to help, but if it's physics related then I'm the person to ask. ^_^
So.. hope this is helpful. ^_^ Just post your questions here in the thread and I'll get to them asap. Please don't pm me with questions as I don't want my mail box full of just science help questions.

k this doesnt consern homework... just curiosity.... i visited a space and science center at child hood and they said said that the earth is actualy oval... but it spins so fast that it gets shaped into a sphere naturaly due to the speed of the spinning, it made sence i thought but what didnt make sence was if i drop a ball why doesnt it land in france or spain... i hope u can answer this casue it has been bothering me for years

When you let fall a ball, it will not fall straight down to the ground, there's a very small deviation, not visible for the human eye if you throw something from about a meter for example. But the friction of the air makes the deviation is not as large as the turning of the air. 2. Another reason is that power of gravity works almost perpendicular on the surface/area (don't know the right English word) of the earth. So it 'pulls' the ball straight down, only leaving the possibility of a very small deviation.

icecurb lol i srry that turned out to be more of a phyics question.. but thanks a bunch lol that's ok. To simplifly what The_Bartner said, we are on a very small scale compared to the earth, so any effects of the earth would be so small we can't detect them. Also gravity works perpendicular to the surface of the earth, so things will also go straight down from where you drop it from and not somewhere else.

icecurb - lol Physics is my speciality, so it's quite alright that it was physics related. Also... did my clearer version help any? ... have you even returned since your last post...?

not quite sure if this is in the right place but heck ill give it a try.
1)is there really such a thing as a blue and blood red moon?
2)what is that thing called with "a body at rest stays at rest a body in motion stays in motion."
i cant remember the last onefor the life of me.

Quote: 1)is there really such a thing as a blue and blood red moon? A blue moon is two full moons in the same month, specifically the name for the second full moon in that month. A more technical explanation can be had here. A red moon is actually dust and other haze in the atmosphere scattering the light coming from the moon, and if you live in an area where there's field burning in the fall, you'll see it a lot. You'll see it most noticeably near the horizon, since the light from the moon is having to travel further through the atmosphere to get to you, and thus is scattered more. Quote: 2)what is that thing called with "a body at rest stays at rest a body in motion stays in motion." Newton's... second law of motion? *goes digging* First law. I knew it was one of them. blaugh You can find basic explanations for each of the three here.
