Awesome sir. Just a question about projectilew and throwing objects to space... Do we nned to consider how far the Earth has moved due to its orbit to calculate how fast it would fall back to earth? Please answer !

@804YankeeFan I would think if we used the Earth as our origin it then mathematically the earth wouldn't "move."

[804YankeeFan]

@jvclark2 so u think it wouldn't move during a short period of time. How about during satellites orbiting it, don't we need to consider the earth's orbit?

@804YankeeFan that's a good point. I'm not sure about that now haha.
