本文全面解析A-Level进阶数学中进阶力学1（FM1）的典型题型。熟练掌握这些常考模式对于高效解题和取得优异成绩至关重要。以下章节涵盖核心主题：冲量与动量、守恒定律、恢复系数、碰撞问题、功能原理、弹性绳、圆周运动和质心。

1. Impulse and Momentum | 冲量与动量

Impulse–momentum questions usually ask you to calculate the impulse given the mass and velocity change, or to find the final velocity after a known impulse. The key formula is I = mv – mu, where I is the impulse vector, m is mass, and u and v are the initial and final velocities. In one dimension, you must pay careful attention to the sign of the velocity depending on the chosen positive direction.

冲量–动量题型通常要求根据质量和速度变化计算冲量，或根据已知冲量求末速度。核心公式为I = mv – mu，其中I为冲量矢量，m为质量，u和v分别为初、末速度。在一维问题中，必须根据选定的
