1) Start running on a treadmill
2) Jump directly sideways off of the treadmill
3) Experience 0 acceleration because your velocity parallel to the treadmill is basically 0.
Note, I think treadmills can work for VR, I'm just here for the physics.
Also, for my third edit, upon re-reading all the comments in this chain, it really seems like we're all agreeing. Just talking about different effects.
- shamino 11y agoThis is the same misunderstanding that many people are having. Your frame of reference while on the treadmill should be the surface of the treadmill. Once you jumped off, you switched your frame of reference to the ground of the earth. Keep your reference on the surface of the treadmill, and you'll see you've experienced negative acceleration. This is why you always get an "extra boost" when you come off the escalator.
- Jack000 11y agoyou can only do this if the surface of the treadmill is an inertial reference frame. ie. a person running at constant speed vs a person on a treadmill at constant speed is functionally equivalent. However, the moment you want to stop or change speed this no longer works - in the real world your body needs to accelerate, while on the treadmill the treadmill accelerates and your body does not. This is because the ground remains an inertial reference frame during the acceleration, while the treadmill surface does not.
