在解物理题或分析物理过程时 ,如果能合理地应用图示法 ,会使物理过程清晰地展现出来 ,让复杂的问题简单化 ,便于分析和理解。下面仅举几例图示法在密度测定中的应用问题 ,以供参考。例 1　现有调节好的天平、砝码、玻璃杯、小金属块、细线和足够的水。请你用上述器材测出金属 In the process of solving a physical problem or analyzing a physical process, if the graphic method can be reasonably applied, the physical process will be clearly displayed, simplifying the complex problem and facilitating analysis and understanding. The following are only a few examples of the application of graphic methods in the determination of density for reference. Example 1 Existing balances, weights, glasses, small metal blocks, fine lines, and sufficient water. Please use the above equipment to measure metal
