    G force deceleration

    I think an astornaut lies towards the Earth's surface. If you think about it, the force experienced by the astronaut, will make him move back, therefore pushing his eyeballs back into their sockets.

    Gravity Question

    Oh yeah. I see. I've edited it now, so it should be right. 0.0 I think you can just memorise. But if you can't then you should derive.

    What is your all time favourite book?

    I wasn't commenting on your choice of books, but you seem to have a long list. Which is a good thing. I personally don't know which book is my favourite, I have read lots, plus there's more to come. I'm more of a movie person :P

    movies vs books

    Same here. If I see a movie that is related to a book, and doesn't have all the best scenes, I hate it. They miss all the good parts. :angry:

    Another Gravity Question

    I think this might be correct. REMEMBER: d is the distance from the centre of the two masses. F=Gm1m2 / d2 F=(6.67 x 10-11) x (7.35 x 1022) x (5.98 x 1024) / ((0.5 x 3467x1000) + (0.5 x 12756x1000) + (406676 x 1000))2 F= 2.9316651 x 1037 / 1.720486702 x 1017 F= 1.70 x 1020 Newtons

    Gravity Question

    Could somebody tell me IF this is wrong: Weight Force =mass x acceleration due to gravity (W=mg) and g=(GM)/r2 sub g=(GM)/r2 into W=mg W= (GmM)/r2 where; G=6.67 x 10-11 m=mass of astronaut M=mass of Earth r=radius of earth (+altitude, if needed) let weight force on EARTH'S...

    No Maths! No Science for yr 11 2009!

    By the subjects that supercalamari and want2beasenior are doing (EX 1, legal, visual arts) they seem to be in the journalism, lawyer, artist sort of fields. So maths and science is not really necessary if they want to do these types of jobs.
