1. Mechanics and Kinematics | 力学与运动学

v = u + a t

Relates final velocity v, initial velocity u, constant acceleration a, and time t.

联系末速度 v、初速度 u、恒定加速度 a 和时间 t。

s = u t + ½ a t²

Gives displacement s in terms of initial velocity, acceleration, and time.

利用初速度、加速度和时间求出位移 s。

v² = u² + 2 a s

Links final velocity, initial velocity, acceleration, and displacement, without involving time.

将末速度、初速度、加速度和位移联系起来，不涉及时间。

s = ½ (u + v) t

Displacement equals average velocity multiplied by time.

位移等于平均速度乘以时间。

Projectile: v_x = u cosθ, v_y = u sinθ – g t

Horizontal and vertical velocity components of a projectile launched at angle θ with initial speed u.

以初速度 u 和角度 θ 抛出的物体，其水平和垂直速度分量。

x = u cosθ ⋅ t, y = u sinθ ⋅ t – ½ g t²

Displacement components in projectile motion under uniform gravity g.

在匀重力 g 作用下的抛体位移分量。

2. Newton’s Laws and Forces | 牛顿定律与力

F = m a

Newton’s second law:
