Hi, If the mass of either M or m is increased, U becomes more negative. This means that the gravitational potential energy is between the 2 object M and m is greater. Note that GPE is a scalar quantity and as such negative work done in bringing a mass m from infinity to a point in a...

Hi, vector diagram: averages out the acceleration of the object between 2 points while centripetal acceleration formula: finds the instantaneous acceleration. The difference lies in using differentiation (the formula) versus the small change in values (the diagram). Then again, when drawing...
