IB 物理与 WJEC A-level 物理共享一套基础原理，这些原理在考试中反复出现。本文总结了学生必须掌握的高频考点，涵盖力学、波动、电学、热物理和近代物理，着重于最常考到的公式和概念。通过整合这些关键领域，你可以精简复习、增强信心，从容应对内部评估和最终考试。

1. Kinematics (Motion) | 运动学

The SUVAT equations form the backbone of kinematics, linking displacement (s), initial velocity (u), final velocity (v), acceleration (a), and time (t). Both IB and WJEC papers frequently require applying these equations to linear motion problems. You must be able to select the correct equation based on the known and unknown variables.

SUVAT 方程是运动学的核心，联系了位移 (s)、初速度 (u)、末速度 (v)、加速度 (a) 和时间 (t)。IB 和 WJEC 的试题经常要求运用这些方程解决直线运动问题。你必须能够根据已知和未知变量选择合适的方程。

v = u + at
s = ut + ½at²
v² = u² + 2as
s = ½
