*NEED HELP ASAP* TIA Hi everyone! If you could help me I would really like that! Question: Suppose the moon rotated on its axis just as quickly as Earth. Would you still always see the same side of the moon from Earth?

@Qwertty123 @4everaddicted2anime

OpenStudy (qwertty123):

What do you think?

OpenStudy (4everaddicted2anime):

I think so, but I'm not sure

OpenStudy (dogzcatz):

If the Moon rotated daily instead of once in the duration 28 days we would see it rotating through out the day. The difference on the moon's surface would show just as fast as the sun is in the sky. ou know how the sun moves that's what i mean

OpenStudy (phoebeiscray152):

I have this much so far but i need more to add before this: Yes, you would see only one side of the moon. A good example why: The only reason we always see the man in the moon is that the moon spins around its own axis at exactly the period it revolves in its orbit around earth. Any other period of rotation would let us see the dark side of the moon

OpenStudy (qwertty123):

if the moon rotated every 24 hrs (like Earth), then you would see different parts of the moon during its orbit

OpenStudy (dogzcatz):

That's what I said

OpenStudy (phoebeiscray152):

So is my theory wrong @Qwertty123

OpenStudy (phoebeiscray152):

I just need more

OpenStudy (qwertty123):

If the Moon rotated once in a day instead of once in 28 days we would see it rotating. The difference on the moon's surface would show just as quickly as the difference of where the sun is in the sky for us,if it goes round once a day. Same speed. The bit of the moon we see would be changing all the time. We would see about 6/7ths of a rotation in 24 hours,not a full rotation. That is because the Moon and Earth move around in their orbits in that 24 hours and we see the Moon from a different direction.. An accurate allowance would need to be made for how much the earth is moving in its orbit and how far the moon moves in it's orbit,if you want to work out very exactly what the rate of rotation would be as seen from Earth. Oh,and all the little wobbles in the orbit too,and the varying orbital speed because the orbit isn't exactly round......Nice bit of maths homework,eh? Some hopes!

OpenStudy (phoebeiscray152):

@Qwertty123 so just to be sure... that means yes?

OpenStudy (qwertty123):

I think so

OpenStudy (qwertty123):

Yes you would!

OpenStudy (phoebeiscray152):

ok thank you!
