物理实验题涉及到多种实验仪器的使用,以及有关公式和原理的应用,有助于提高学生的实践能力和科学素养.一、熟悉仪器性能例1给你一把刻度尺,一支弹簧测力计,一支温度计,一块秒表和一长方形木块,你能直接或间接测量哪些物理量?解析直尺、弹簧测力计、温度计、秒表可直接测量长度、重力、温度和时间·用弹簧测力计和直尺测得质量m和体积V,运用ρ=m/V,可得密度;还可 Physical experiment involves the use of a variety of experimental instruments, as well as the application of formulas and principles, to help improve students' practical ability and scientific literacy. First, familiar with the instrument performance Example 1 gives you a scale, a spring Gauge, a thermometer, a stopwatch and a rectangular block, which physical quantities can you measure, directly or indirectly? Analyze ruler, spring force gauge, thermometer, stopwatch for direct measurement of length, gravity, temperature and time. Force gauge and ruler measured mass m and volume V, the use of ρ = m / V, available density; also
