We watch while orbiting with them two untethered space walking astronauts. One of them needs to get from the International Space Station's hatch to another place outside to service a failing pump. If they have no hand on the station, and one of them pushes on the other to send his co-worker over to the location needing service, what would consequently happen to the first astronaut? He would go along with his companion but at a different speed because of their different masses. He would go in the opposite direction with nearly equal constant speed, and eventually be lost in space. He would remain stationary while his companion drifted away. He would go in the opposite direction but slow down and stop drifting. Riding in a car, you suddenly put on the brakes. As you experience it inside the car, do Newton's law apply? Do they apply as seen by someone outside the car? They do not apply from your frame of reference, but they do apply as seen by someone stationary or moving at a constant speed outside your car. They do apply from your frame of reference, and they also apply as seen by someone stationary or moving at a constant speed outside your car. They do from your frame of reference, but they do not apply as seen by someone stationary or moving at a constant speed outside your car. They do not apply at all for any observer.
