All of those would still happen in zero-g though right?
- sandworm101 4y agoYes. Toss a cat off a roof and the cat experiences "zero-g" as it accelerates towards terminal velocity.
- geph2021 4y agothe cat experiences "zero-g" as it accelerates towards terminal velocity I think you meant the cat experiences 'zero-g' AFTER it's done accelerating and has reached terminal velocity. I'm guessing in most cat falling situations the cat does not reach terminal velocity, so it is accelerating the whole time and can adjust based on the direction of acceleration.
- sandworm101 4y agoNo. Terminal velocity is one-g, the same as sitting in a chair. A skydiver at terminal velocity feels exactly as much force/acceleration from the wind as they would feel force from lying down on the ground.
- gricardo99 4y agoThat's right, the forces cancel each other out, so that's "zero-g". If you're accelerating, you're experience some "g" force, not "zero-g".
- sandworm101 4y agoExcept acceleration due to gravity. Freefall is acceleration without feeling any apparent force.
- chrischen 4y agoI’m sitting on the toilet right now, and the forces are canceling each other out so that I’m not sitting in the toilet. Is this 0g?
- klysm 4y agoI don’t think you experience zero g, you feel acceleration right?
- sandworm101 4y agoHaving done "zero-g" in aircraft many times, you do feel it. Your blood shifts. Your spine decompresses. Your head gets lighter. You very much know that you are falling.
- IncRnd 4y agoThat's not true zero-g. In a plane you are experiencing the force of acceleration towards Earth, which is closer to 1G than to 0G.
- sandworm101 4y agoI can assure you that while being trained in basic aerobatics we regularly went well beyond the zero-to-one G range.
- sacrosancty 4y agoA lot of confusion here probably comes from the fact that g-force is not the same as acceleration. It's apparent acceleration. So 0g in an aircraft is entirely possible. So is 0 acceleration but that's not 0 g, that's 1 g.
- vba616 4y agoWhen do people mean anything other than "free fall" by "zero g"?
- chewbacha 4y agoYea, but since the air in the plane is also in free fall it’s moving with the cat and thus doesn’t provide appropriate signal.
- ehnto 4y agoIf you have a cat in a cylinder of air in space, and push it toward one end of the cylinder, I think it would get those signals since the cat is being pushed through the air.
