📚 Quick Reference Handbook of Formulae and Theorems | 工程公式定理速查手册
This handbook provides a concise summary of essential formulae and theorems for CCEA Year 10 Engineering. Mastering these relationships will support your design calculations and problem-solving across mechanics, electronics, and materials.
本手册为CCEA十年级工程课程的核心公式与定理速查总结。掌握这些关系式有助于你在力学、电子学和材料学等领域进行设计计算和问题求解。
1. Force, Mass and Acceleration | 力、质量与加速度
Newton's Second Law of Motion is the foundation of dynamics: the resultant force acting on an object equals the product of its mass and acceleration.
牛顿第二运动定律是动力学的基础：作用在物体上的合力等于物体质量与加速度的乘积。
F = m × a
; 9.81 m/s² on Earth. If multiple forces act, always determine the resultant force first.
重力是一种由引力产生的特定力：W = m × g，地球上 g ≈ 9.81 m/s²。若有多个力作用，请始终先求出合力。
W = m × g
2. Motion: Speed, Velocity and Acceleration | 运动：速度、速率与加速度
Average speed is total distance divided by time. Acceleration is the rate of change of velocity.
平均速率是总距离除以时间。加速度是速度的变化率。
