    Change in momentum for a satellite in circular orbit

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

    Change in momentum for a satellite in circular orbit

    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?

    Change in momentum for a satellite in circular orbit

    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...
