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.

- How is moment of inertia measured?
- A wheel rotating with a uniform acceleration covers 100 revolution in the first 10 seconds after the start. What is the angular velocity at the end of 10 seconds?
- A cylinder has inner and outer radii of #16 cm# and #18 cm#, respectively, and a mass of #2 kg#. If the cylinder's frequency of rotation about its center changes from #4 Hz# to #9 Hz#, by how much does its angular momentum change?
- What is the angular momentum of an object with a mass of #7 kg# that moves along a circular path of radius #2 m# at a frequency of # 5 Hz #?
- A cylinder has inner and outer radii of #9 cm# and #12 cm#, respectively, and a mass of #9 kg#. If the cylinder's frequency of counterclockwise rotation about its center changes from #1 Hz# to #7 Hz#, by how much does its angular momentum change?
