Discussion Overview

The discussion centers around the scenario of an astronaut attempting to shake an anvil in outer space, focusing on the dynamics of motion and force between two objects of differing mass. Participants explore the implications of mass on movement and the interaction of forces in a microgravity environment.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests that if the astronaut's hands are strong enough, he could remain stationary while attempting to shake the anvil.
  • Another participant argues that the anvil would shake the astronaut due to the equal and opposite forces acting on both, questioning why this wouldn't be the case.
  • It is proposed that the astronaut would experience more movement than the anvil because of the anvil's greater mass.
  • A similar point is reiterated, emphasizing that if the astronaut were to push off a wall in the ISS, he would not significantly alter the station's orbital path, implying a misunderstanding of mass and force interactions.
  • One participant humorously notes that such an outcome would require breaking several rules of physics.

Areas of Agreement / Disagreement

Participants express differing views on the effects of mass on movement and the interaction of forces, indicating that the discussion remains unresolved with multiple competing perspectives.

Contextual Notes

The discussion involves assumptions about the strength of the astronaut's hands and the nature of forces in a microgravity environment, which may not be fully articulated or agreed upon.

let's assume that an astronaut is trying to shake an anvil that is more massive than him ,,,,,, this happens in outer space what would shake more the astronaut or the anvil ?? why ??
 
Physics news on Phys.org


If your hands are strong enough, you can stay put.
 


It is equally easy to understand that the anvil is shaking the man, since the forces are equal and opposite, so why not?
 


The astronaut would move himself more than he would move the anvil precisely because the anvil is more massive than he is.

I guess if the opposite were true, every time an astronaut inside the ISS pushed off the side wall to manuever , they'd push it out of it's orbital path ?

Only if several rules of physics are broken. =)

Well we certainly can't let them get away with that...:eek:
