Thanks a lot, that was a big help. I hadn't caught that the centripetal force equation was only for circular orbits.

Aha, then the equation F=\frac{mv^2}{R} only holds true for circular motion then, and thus R can never be varied, correct? Or, R can be varied, but it must be computed as the radius of curvature of motion rather than the distance of the object from the center.

Hi, I was just going over some equations for velocity with respect to bodies revolving around the sun. I wanted to figure out the ratio of tangential linear velocity (i.e. speed) of a body when it is at its perihelion to its velocity at aphelion. In other words, I wanted to solve for...
