🚀 加速度计算器Acceleration Calculator
用速度变化与时间、力与质量，或距离与时间计算加速度，并换算为 g 值。Calculate acceleration from change in velocity over time, force and mass, or distance and time, and express it in g.
使用说明与常见问题How-to & FAQ
「加速度计算器」是什么？What is the Acceleration Calculator tool?
用速度变化与时间、力与质量，或距离与时间计算加速度，并换算为 g 值。Calculate acceleration from change in velocity over time, force and mass, or distance and time, and express it in g.
如何使用「加速度计算器」？How do I use the Acceleration Calculator tool?
在「加速度计算器」中，填写「计算方式」、「初速度 v₀ (m/s)」、「末速度 v (m/s)」、「时间 t (s)」、「力 F (N)」等参数，结果会随输入实时计算并显示在下方。In the Acceleration Calculator: Fill in "Method", "Initial velocity v₀ (m/s)", "Final velocity v (m/s)", "Time t (s)", "Force F (N)"; results are recalculated instantly as you type.
减速时加速度为负吗？Is deceleration negative?
是的，末速度小于初速度时结果为负值，表示加速度方向与运动方向相反。Yes. If the final velocity is lower than the initial one the result is negative: the acceleration points against the motion.
1 g 是多少？What is 1 g?
标准重力加速度 g = 9.80665 m/s²（国际定义值）。Standard gravity is g = 9.80665 m/s² (defined value).
计算结果可以用于作业或工程吗？Can I use the results for homework or engineering?
「加速度计算器」使用教科书标准公式（公式写在说明和常见问题中），适合学习和估算核对；涉及安全的工程设计请以规范和实测为准。The Acceleration Calculator uses standard textbook formulas (given in the description and FAQ), which is good for learning and checking estimates; for safety-critical engineering follow codes and measured values.
