Well the change in velocity/momentum would be a negative value relative to its original position. Ahhh, I see.. assign +ve and -ve.. Thanks

So I'd be wrong to say that the magnitude of the relative velocity does not change in circular orbit? I'm aware the nature of the direction does, and that velocity is a vector quantity - but how does that produce a quantifiable change in momentum?

Homework Statement A satellite is in a circular orbit passing over the North and South geographical poles as it orbits the Earth. It has a mass of 2200kg and its orbit height is 870km above the Earth's surface. What is the change in momentum of the satellite from when it passes over the...

Hey all. Glad to have found this forum. I'm currently studying a Bachelor of Science majoring in physics and nanotechnology at Murdoch University, Western Australia. I look forward to participating in discussions. Thanks. :)
