Yes. Toss a cat off a roof and the cat experiences "zero-g" as it accelerates towards terminal velocity.
- klysm 5y agoI don’t think you experience zero g, you feel acceleration right?
- sandworm101 5y 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 5y 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 5y agoI can assure you that while being trained in basic aerobatics we regularly went well beyond the zero-to-one G range.
- sacrosancty 5y 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 5y agoWhen do people mean anything other than "free fall" by "zero g"?
- geph2021 5y 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 5y 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 5y 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 5y agoExcept acceleration due to gravity. Freefall is acceleration without feeling any apparent force.
- chrischen 5y 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?
