How does the law of conservation of matter and energy relate to the cycles in nature?
The law of conservation of matter and energy states that matter is neither created nor destroyed but conserved.

The law of conservation of matter and energy states that matter and energy cannot be created or destroyed, only transformed from one form to another. In nature, various cycles, such as the water cycle, carbon cycle, and nitrogen cycle, demonstrate this law by showing how matter and energy are continuously recycled and redistributed through different processes and organisms. For example, in the water cycle, water evaporates from bodies of water, condenses into clouds, precipitates as rain or snow, and then flows back into bodies of water, repeating the cycle. Throughout these cycles, matter and energy are conserved, illustrating the principles of the conservation of matter and energy in action.

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.

- An object with a mass of #4 kg# is hanging from an axle with a radius of #8 cm#. If the wheel attached to the axle has a radius of #24 cm#, how much work would it take to turn the wheel #4 cm#?
- An object with a mass of #2 kg# is hanging from an axle with a radius of #2 cm#. If the wheel attached to the axle has a radius of #8 cm#, how much work would it take to turn the wheel a length equal to the circumference of the axle?
