Why in all space movies, except "2001", is there man made gravity to hold the characters on the floor?
but then when somebody takes a shuttle to the surface of a world, they pretty much have to rely on aerodynamics and rocketry instead of zero gravity, thus the scenes where they come burning in and lose control instead of just floating down to the surface?
In the future could we focus gravity on a point in space and contract space so we can cross it more quickly?
Specific gravity question?
Assume gold has a specific gravity of 20, and a five gallon bucket of water weighs 40 pounds. How many pounds would a five gallon bucket of gold weigh?
Could the winter solstice alignment of the planets in 2012 effect earths gravity?
I ask this question because I have slightly become obsessed with this whole 2012 end of the world thing.I am no physicist .So my theories are completely uneducated .But I wonder..If the sun will rise in the center of the galaxy were there is a known gigantic blackhole could the gravity of a super massive blackhole combined with the gravity of the other aligned planets act as a vacuum effect on earth ?That pulls us closer to the sun.Or maybe pulling the sun further away into its massive gravity deathlock freezing the earth?All the speculation of these events and the uncertainty drives me nuts.It seems like our best and brightest cannot even wrap their big brains around it.Its a huge mystery.But I was hoping maybe some more intelligent folks than I have a theory of their own.I would love to hear it.Im glad I asked this question.Even if it does make me look like a moron.The fact this was created as a hoax to scare people or to make for interesting television viewing totally makes sense.I guess I was sucked in along with all these other people that the end was near.I have done some research on the maya calendar .And from I have read there are calendars that go beyond 2012.I guess I shouldnt believe everything I see or read.I believe the earth will not last forever science has proved that But it will not end in 2012.I have also read that nostradamus predicted the world to end in 3787 or 3797 .But I guess we will never know about that one.Thank you for all your intelligent responses.You all have made me feel better and maybe shed some light on someone else who might have the same ideas as I had.
Another gravity and newton question?
1. The following diagrams are the same as those from Part A. This time, rank the pairs from left to right based on the size of the acceleration the asteroid on the left would have due to the gravitational force exerted on it by the object on the right, from largest to smallest.asteroid sunasteroid hydrogen atomasteroid asteroidasteroid earthasteroid moon
Physics problem dealing with gravity!?
The acceleration due to gravity on the moon is 1 6 of its value on earth. If a basketball player has a vertical jump of 1.2 m on earth, what is his theoretical vertical jump on the moon?
Why can't light escape a black hole? Because it's not affected by gravity..right?
doin a project
Why is it significant to have 4 degrees C of water in specific gravity?
How to find initial Velocity given height and acceleration due to gravity?
I need help finding which equation to use. A ball is thrown horizontally from a height of 20.95 m and hits the ground with a speed that is 4.0 times its initial speed. What was the initial speed? Can someone get me started in solving this?
Is there a way to experience no gravity? On shows, or on tv?
Is there any way to make it appear that there is no gravity? Having a debate with my husband...Besides the obvious, like falling from the sky superey duperey fast...?I can tell if it was a green screen or something.... It wouldn't be the same under water if it was in some sort of container...?
What is the realy reson of gravity?
If the laws of physics were made after the big bang,how can Stephen Hawking say that gravity inevitably led?
to the Big Bang??According to current thought, the laws of physics including gravity were 10 36 seconds after the Big Bang, so how can the laws of physics inevitably lead to the big bang when they were made after the big bang?
Density and specific gravity question!?
the specific gravity of a liquid is 0.894. what is its density water is the referent
Why does Stephen Hawking say that there is a ''law such as gravity''?
when Einstein s general relativity proved there is no such thing?news.yahoo.com s nm 20100902 lf nm life us britain hawking
