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...
