1. Kinematics – Linear Motion | 运动学 – 线性运动

Average velocity (v) is displacement per unit time: v = Δs / Δt. When direction is constant, it simplifies to v = d / t where d is total distance travelled.

平均速度 (v) 是单位时间内的位移：v = Δs / Δt。当方向不变时，可简化为 v = d / t，其中 d 为总行驶距离。

Acceleration (a) measures the rate of change of velocity: a = (v – u) / t, where u is initial velocity and v is final velocity.

加速度 (a) 度量速度变化的快慢：a = (v – u) / t，其中 u 为初速度，v 为末速度。

The SUVAT equations describe uniform acceleration: v = u + a t ; s = u t + ½ a t² ; v² = u² + 2 a s ; s = ½ (u + v) t. These are fundamental for analysing sprints, throws and jumps.

SUVAT 方程描述匀加速运动：v = u + a t ；s = u t + ½ a t² ；v² = u² + 2 a s ；s = ½ (u + v) t。这些是分析短跑、投掷和跳跃动作的基础。
