How do mass and distance affect gravitational force?
Layla AhmedGravity increases with mass Directly proportional.
Gravity reduces inversely proportional;l to square of distance.

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 #9 MG# and #7 MG#. How much does the gravitational potential energy between the objects change if the distance between them changes from #36 m# to #45 m#?
- A model train, with a mass of #12 kg#, is moving on a circular track with a radius of #9 m#. If the train's kinetic energy changes from #36 j# to #27 j#, by how much will the centripetal force applied by the tracks change by?
- A model train, with a mass of #2 kg#, is moving on a circular track with a radius of #3 m#. If the train's kinetic energy changes from #4 j# to #5 j#, by how much will the centripetal force applied by the tracks change by?
- A model train, with a mass of #8 kg#, is moving on a circular track with a radius of #1 m#. If the train's rate of revolution changes from #3/5 Hz# to #5/6 Hz#, by how much will the centripetal force applied by the tracks change by?
