When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- Two objects have masses of #42 MG# and #26 MG#. How much does the gravitational potential energy between the objects change if the distance between them changes from #8 m# to #9 m#?
- A model train, with a mass of #5 kg#, is moving on a circular track with a radius of #9 m#. If the train's rate of revolution changes from #5 Hz# to #9 Hz#, by how much will the centripetal force applied by the tracks change by?
- An object with a mass of #2 kg# is revolving around a point at a distance of #5 m#. If the object is making revolutions at a frequency of #2 Hz#, what is the centripetal force acting on the object?
- A model train, with a mass of #6 kg#, is moving on a circular track with a radius of #7 m#. If the train's rate of revolution changes from #4 Hz# to #0 Hz#, by how much will the centripetal force applied by the tracks change by?
