Okay, I need to write a professional wiki-style document about balls in Korean. Let me start understanding the structure and requirements The main category is Sports, then Field Sports, and the specific topic is Golf Equipment, with the title being Golf Ball.

First, document should have a clear1 title. The title in Korean would be "골프공". Then there's an overview or introduction section. I should explain what a golf ball is, its basic role in the game, and maybe mention its evolution over time. I need to make sure the information is accurate and objective.

Next, the detailed sections. The user mentioned using H2 and H3 headings. Let me think about possible sections. Maybe the structure of a golf ball, materials used, types of golf balls, selection criteria, maintenance, and recent trends. Each of these can be a H2 section. Under each H2, I can have H3 subsections. For example, under structure, I can talk about core, mantle, cover. Materials might include rubber, urethane, ionomer. Types could be 2-piece, 3-piece, multi-layer. Selection could cover hardness, spin, distance vs control. Maintenance would include cleaning, storage, checking for damage. Trends might involve environmental impact and technology.

I need to ensure each section has enough depth. For instance, explaining the core's role in compression and energy transfer. The cover material affecting spin and durability. Different types of balls suited for different player levels. When discussing selection, maybe mention how beginner vs professional players might choose different balls. Maintenance tips like avoiding extreme temperatures and using proper cleaning methods.

I should also include a references or related documents section. Maybe link to articles on golf clubs, rules of golf, or famous golf tournaments.

Now, checking the markdown format. Use H1 for the title, H2 for main sections, H3 for subsections. Use bullet points where appropriate, maybe tables if needed, but since the user didn't specify, maybe just lists. Technical terms like "코어", "맨틀", "커버" should be explained briefly. For example, when talking about urethane cover, mention that it's soft for better spin control but less durable.

Need to make sure the text is over 800 characters. Let me estimate. The example response the user provided is around 2000 characters. So I need to elaborate each section sufficiently. Maybe add more details in each subsection. For example, in the history part, mention the featherie and gutta-percha balls. In materials, specify which companies use which materials, like Titleist uses urethane for their Pro V1.

Also, avoid markdown in the thinking process, but the final answer should be in markdown. So I need to structure the document properly with # for H1, ## for H2, ### for H3. Use bold for technical terms when first introduced, maybe italics for emphasis. Code blocks for any technical specs, but since it's about golf balls, probably not necessary unless mentioning specific models or numbers.

Check for any inaccuracies. For example, confirming that modern golf balls have a core, one or more mantle layers, and a cover. Also, the dimple pattern's effect on aerodynamics. Mention that the USGA and R&A regulate the minimum size and weight. The standard diameter is at least 1.68 inches, weight no more than 1.62 ounces.

In the selection section, discuss how ball hardness affects performance. Softer balls for more spin and control, harder for distance. Different player types: high handicappers might prefer distance balls, low handicappers might prefer multi-layer for control.

Maintenance: Cleaning with soapy water, avoiding leaving in cars, checking for cuts or abrasions which can affect flight.

Trends: Biodegradable balls for environmental reasons, especially for driving ranges. Smart golf balls with sensors for training, though they're not legal in official play.

References: Link to USGA rules, articles on golf equipment, maybe some manufacturer sites.

Now, putting it all together in Korean, making sure each section flows logically, using appropriate headings, bullet points, and explanations. Keep the language professional but accessible, avoiding overly technical jargon unless explained. Check that all sections meet the requirements and the total length is sufficient.
