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.

- If 'g' is the acceleration due to gravity on earth then increase in P.E of a body of mass 'm' up to a distance equal to the radius of earth from the earth surface will be ?
- Two objects have masses of #9 MG# and #5 MG#. How much does the gravitational potential energy between the objects change if the distance between them changes from #24 m# to #48 m#?
- A model train with a mass of #4 kg# is moving along a track at #18 (cm)/s#. If the curvature of the track changes from a radius of #25 cm# to #42 cm#, by how much must the centripetal force applied by the tracks change?
- A model train, with a mass of #5 kg#, is moving on a circular track with a radius of #1 m#. If the train's kinetic energy changes from #25 j# to #40 j#, by how much will the centripetal force applied by the tracks change by?
- A model train with a mass of #3 kg# is moving along a track at #8 (cm)/s#. If the curvature of the track changes from a radius of #12 cm# to #16 cm#, by how much must the centripetal force applied by the tracks change?
