| Feb 2, 2016 at 15:23 | comment | added | Kevin Fegan | How would it matter where you were in this scenario. Would you expect the outcome of the Earth-machine collision to be any different if you, with your remote, were located on Earth, or on the Moon, or just floating somewhere in space? (other than the effect of your own mass being present or not-present on Earth) | |

| Nov 2, 2015 at 14:19 | comment | added | Kyle Kanos | As ACuriousMind says, this is simple application of Newton's 3rd. You're probably overthinking it. | |
| Nov 2, 2015 at 14:15 | comment | added | SchrodingersCat | @KyleKanos Internal force (like using hands only).. That's impossible. But that is what my analogy of the Situation reads as in the question. I know its not right. That's where I am confused. | |
| Nov 2, 2015 at 14:08 | comment | added | ACuriousMind♦ | By Newton's third law, the machine pushing the earth experiences a equal and opposite force. So the center of mass of the system earth+machine does not move since the net force on it is zero. I'm not sure where your confusion lies. | |
| Nov 2, 2015 at 13:30 | comment | added | Kyle Kanos | What do you mean pushing the chair forwards? How are you pushing it (e..g, feet on ground, just hands only)? | |
| Nov 2, 2015 at 13:26 | comment | added | SchrodingersCat | @KyleKanos Edited the question. Does it make sense now? | |

| Nov 1, 2015 at 16:09 | comment | added | SchrodingersCat | @DavidZ I have explained what I really meant by invisible\imaginary hand. | |
| Nov 1, 2015 at 15:50 | comment | added | David Z | More like the latter. Your "invisible hand" force is not valid physics. | |
| Nov 1, 2015 at 14:34 | comment | added | SchrodingersCat | @DavidZ Why do you think this question is off-topic? Newtonian mechanics does not involve real physics or the question does not involve newtonian physics? | |

| S Nov 1, 2015 at 12:03 | comment | added | David Z | I'm voting to close this question as off-topic because it's not about real physics. | |
| Oct 31, 2015 at 19:22 | comment | added | Asher | @Aniket But you seem to think that because you are holding a remote control, the force moving the Earth is internal to the Earth-machine system, when in reality it is external force from the rocket exhaust. Or you include the exhaust, and the COM doesn't move. But you're ignoring the propulsion system entirely. | |
| Oct 31, 2015 at 8:25 | comment | added | SchrodingersCat | @Asher Perhaps you didn't understand what I meant by an imaginary hand. I am interacting with the machine and that is what I meant by imaginary hand. There's nothing magic, its just crooked physics. | |
| Oct 30, 2015 at 19:56 | comment | added | Asher | @Aniket if you're asking what would happen if you could move Earth with magic, this isn't a physics question. If you're asking about moving Earth with rockets on a mecha then it's a physics question. Rockets aren't "imaginary hands" though, so you'll have to choose one or the other. | |

| Oct 30, 2015 at 19:15 | comment | added | SchrodingersCat | @WillO Why do you say "Clicking a switch or moving a slider cannot, by itself, change the path of a big machine"? Even if it cannot, assume it does. Still the problems can be resolved... | |

| Oct 30, 2015 at 19:01 | comment | added | Yorik | I think you have pointed out your own mistake: the italicised portion of your question. | |
| Oct 30, 2015 at 19:00 | comment | added | WillO | You should take @AritraDas 's comment more seriously. Clicking a switch or moving a slider cannot, by itself, change the path of a big machine. Clicking the switch can fire a booster rocket, though. | |

| Oct 30, 2015 at 18:53 | comment | added | SchrodingersCat | @AritraDas I want to do it via my remote control. One click and it speeds up. Another switch clicked and it stops. I move a slider and the direction of the machine's path is changed. In this way. | |
| Oct 30, 2015 at 18:50 | comment | added | Aritra Das | How do you propose to "increase the speed of the machine" or change it's "speed, direction, acceleration"? If you use booster rockets, then it is not a part of your Earth-you system. If you really mechanically push it from Earth, you'll change Earth's velocity accordingly such that the center of mass of Earth-you-machine system is unmoved. | |
