Title: how do g's happen
Post by: cdmanm on November 18, 2008, 07:52:45 PM
i know g's is gravity but how does it add more when you do a break turn?

Was going to try and explain it, then thought better...

i just saw this but why pushing up on the mouse make a crash it doesn't make sense to me  :confused:

Any chance you could be a little more detailed ?

I'm assuming level flight here but pushing up (towards the monitor) on the mouse would be the same as pushing forward on the stick or yoke in an aircraft. This would force the nose down towards the ground.

simply really....


rollercoaster... when u drop and u rise out of your seat?  neg g...

when you go around a corner or thru a loop and get pressed in your seat.. positive g...

you can do some research on rollercoaster g-forces and then use that as sort of a baseline comparison to what 4-9gs might feel like. 

not gonna go all scintificient or whatever on you....  fluid dynamics, mass, momentum, inertia, yanno  physics and physiology crap like that :aok

Newton's first law? An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an outside force.  Your plane is changing direction, but your bodys momentum wants to continue to move in a straight line.  The more abrubt the direction change the greater the force the pilot feels.  The plane itself is also loaded with this force.

Push the mouse up, houses get smaller.

Push the mouse down, houses get bigger.

thinkin same thing after i saw OP  :O

Direct relationship between speed, control input, and G force.

The faster you are, or the bigger the input, the more G's you'll feel.

Picture a common Elevator in a tall building. When it starts up, your moving, changing state from being at rest, to traveling Upward. So you feel a little G bump, pulling you down, maybe flexing your knees. Your not moving real fast, so the gee's felt are not that strong. As that acceleration upward continues you feel "heavy"

As the elevator starts slowing down for its stop, you'll feel negitive gee's. Its been moving you up steady, now it cuts the gas, reducing the input. You feel "light" for a second.

Now take that elevator and instead of moving at 5 miles an hour put wings on it and its moving at 3-400 mph.
What happens when you pull the stick back and it goes up? Its going up a mile in seconds.

Righto, blackout, 6 Gee's. And if you pushed the stick forward, same thing, only redout. Shoves the fluid in your body into your head. (Can pop blood vessels in your eyes btw)
