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 do matter and energy interact?
- A ball with a mass of #150 g# is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of #18 (kg)/s^2# and was compressed by #7/5 m# when the ball was released. How high will the ball go?
- A balanced lever has two weights on it, the first with mass #2 kg # and the second with mass #1 kg#. If the first weight is # 7 m# from the fulcrum, how far is the second weight from the fulcrum?
- A ball with a mass of #256 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 #24/5 m# when the ball was released. How high will the ball go?
- An object with a mass of #8 kg# is hanging from an axle with a radius of #27 m#. If the wheel attached to the axle has a radius of #18 m#, how much force must be applied to the wheel to keep the object from falling?
