Corey Posted December 11, 2004 Share Posted December 11, 2004 [size=1]I might be wrong now that you brought that to my attention Sciros. I'm going to ask my physics teacher on Monday. EDIT- Gravity has absolutely no sway over horizontal motion. My physics teacher drilled this into our head. If you roll that ball off of a table at 5 meters/second horizontally it's going to stay at 5 meters/second until something acts on it to make it slow down, like hitting the floor. If you could find a table high enough for the ball to fall hundreds of years, it would be going faster than hell downwards, but still 5 meters/second horizontally. EDIT 2- Also acceleration is (for example) 5 meters/second every second. It looks like this. [center][u]5 meters/second[/u] second[/center] A 5 meters/second just means that you cover 5 meters every second. Just a good thing to keep in mind.[/size] Link to comment Share on other sites More sharing options...
Baron Samedi Posted December 11, 2004 Share Posted December 11, 2004 [size=1]Earth's gravity is 9.8m/s^2 Meaning that in one second, [a to b] you'll travel 9.8 metres, but in the next second [b to c] you will travel 19.6 metres. It increases exponentially from there. Anyway, Adahn, an object with no forces acting upon it, will remain at rest. Once affected by a net-force, if no other forces are applied [as may be found in an empty space] it will continue in that direction. Forever. This is Newtons [2nd?] Law. Which explains why momentum works in space. Imagine it as being a car...you are at rest, until the car moves forward. Then, until you 'acclimatise' yourself to the speed, you are experiencing lateral pressure. It still works in space.

Delta Posted December 11, 2004 Share Posted December 11, 2004 [COLOR=DarkRed][SIZE=1]I think it's the First Law(Law of Inertia). An object will remain at rest/travel in the same constant velocity unless acted upon by an external net force. And why you get slammed forward when a car you're in suddenly stops is because of inertia. Momentum, I think, only comes into equation when bodies collide with each other. It sort of predicts their motion after the collision. On to the topic: Yeah, the machine that will counteract G-forces is yet to be invented, but who knows? MAybe it already exists and we just don't know about it? Love and Peace! [/SIZE][/COLOR] Link to comment Share on other sites More sharing options...

Ok, even if we were to accelerate slowly towards the speed of light such that the force on the body is tolerable, that doesn't mean the body will behave normally with the concentration of energy it has.

Wormholes aren't about speed at all, and the energy burst from matter/antimatter would need a container for the energy released (i.e., more mass).

In this example, in ONE second, you'll be moving at a speed of 5 meters/second, which, if you stopped accelerating, would take you 5 meters in ONE second. Trivial correction, I know, but I was getting confused, which brings me to my question: I'm intrigued but lost on where this discussion is heading. What's so important about g-forces with respect to going at the speed of light?[/COLOR][/SIZE][/FONT] EDIT #1: After thinking about it, I think it would be of great benefit to both sides of whatever argument to work from the ground up.

Baron Samedi Posted December 11, 2004 Share Posted December 11, 2004 [size=1]I was referring to earth's gravity, which no-one seemed to be making clear was 9.8m/s^2, not merely 9.8m/s Sorry, lol. The first is acceleration, the second velocity, yes. Ok, back to the roots. Do I think light-speed travel will ever be possible? No. Do I consider there to be more possiblity of dimensional travel?
