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.

- What is the gravitational potential energy of a # 21 kg# object on a shelf # 5 m # high?
- A ball with a mass of #300 g# is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of #32 (kg)/s^2# and was compressed by #5/6 m# when the ball was released. How high will the ball go?
- How do you calculate the efficiency of a simple machine?
- An object with a mass of #4 kg# is hanging from an axle with a radius of #18 cm#. If the wheel attached to the axle has a radius of #24 cm#, how much work would it take to turn the wheel #16 cm#?
