欢迎开启你的寒假工程复习计划。这份系统化的指南专为 Year 10 学生设计，旨在巩固 SQA 工程科学课程的核心专题，涵盖力学系统、电子学、气动系统、材料以及设计流程。按照本计划学习，你能在假期中高效强化理解、练习解题，为即将到来的考核建立信心。
1. Setting Your Revision Goals | 设定复习目标
Before diving into content, define clear, achievable goals for the winter break. For example, aim to complete one topic every two days, attempt five past-paper questions per session, and identify three personal weak areas to prioritise.
在进入具体内容之前，先为寒假设定清晰可实现的目标。例如，确定每两天完成一个专题、每次复习尝试五道历年真题，以及找出三个最需要优先攻克的薄弱环节。
2. Forces and Linear Motion | 力与直线运动
Revise Newton's three laws of motion and understand how unbalanced forces cause acceleration. Use the equation F = m × a to link force, mass, and acceleration. Draw free-body diagrams to resolve forces into components and calculate net force.
复习牛顿三大运动定律，理解不平衡力如何产生加速度。运用公式 F = m × a 将力、质量和加速度联系起来。绘制受力分析图，对力进行分解并计算合力。
Practise problems involving friction and air resistance. Remember that when forces are balanced, an object moves at constant velocity or stays at rest. This concept is crucial for analysing vehicles and structures.
练习涉及摩擦力和空气阻力的问题。记住，当力平衡时，物体保持静止或匀速直线运动；这一概念对分析车辆和结构至关重要。
3. Moments, Torque and Equilibrium | 力矩、扭矩与平衡
A moment is the turning effect of a force, calculated using M = F × d, where d is the perpendicular distance from the pivot. For a system in rotational equilibrium, the sum of clockwise moments equals the sum of anticlockwise moments.
力矩是力的转动效应，由公式 M = F × d 计算，其中 d 为距支点的垂直距离。系统处于转动平衡时，顺时针力矩之和等于逆时针力矩之和。
Torque is the equivalent term in engineering for the twisting force applied to shafts and gears. Apply these principles to solve lever, beam, and gear-train problems, paying close attention to the position of the pivot and the direction of each force.
扭矩是工程学中专指施加在转轴和齿轮上的扭转力矩。运用这些原理解决杠杆、横梁和齿轮系的问题，特别留意支点位置和每个力的方向。
4. Work, Power and Efficiency | 功、功率与效率
Work done is energy transferred when a force moves an object, found by W = F × s. Power is the rate of doing work: P = E / t or P = W / t. Efficiency compares useful output to total input: η = (useful power output ÷ total power input) × 100%.
功是力移动物体时传递的能量，公式为 W = F × s。功率是做功的速率：P = E / t 或 P = W / t。效率将有用输出与总输入进行比较：η = (有用功率输出 ÷ 总功率输入) × 100%。
Link these concepts to mechanical systems such as motors, pulleys, and ramps. Calculate efficiency losses due to friction and heat, and be able to suggest improvements in system design to conserve energy.
