恒定加速度（Constant Acceleration）是物理學中描述物體運動狀态的核心概念，指物體在運動過程中速度隨時間均勻變化的特性。具體表現為單位時間内速度的變化量（即加速度）保持不變，其數學表達式為：
$$
a = frac{Delta v}{Delta t}
$$
其中，( a ) 表示加速度，( Delta v ) 是速度變化量，( Delta t ) 是時間間隔。
運動學方程
恒定加速度下，物體的位移（( s )）和速度（( v )）可通過以下公式描述（來源：Georgia State University《HyperPhysics》）：
$$
v = v_0 + at
s = v_0 t + frac{1}{2} a t
$$
這裡 ( v_0 ) 為初速度，( t ) 為時間。
牛頓第二定律關聯
當物體所受合力恒定時，其加速度恒定。例如，自由下落的物體（忽略空氣阻力）僅受重力作用，加速度為重力加速度 ( g approx 9.8 , text{m/s} )（來源：NASA《運動學基礎》）。
工程與日常場景
恒定加速度模型廣泛應用于汽車加速測試、電梯運動設計等領域。例如，汽車以固定油門加速時，可近似為恒定加速度運動（來源：MIT《經典力學導論》）。
通過上述理論框架與實例，恒定加速度的概念在科學研究和工程實踐中均具備明确的定義與應用價值。
"Constant acceleration"（恒定加速度）是物理學中描述物體運動狀态的一個術語，具體含義如下：
恒定加速度指物體在運動過程中，加速度的大小和方向均保持不變。這意味着物體的速度隨時間以均勻的速率變化。例如，忽略空氣阻力時，自由下落的物體因重力産生的加速度接近恒定（約9.8 m/s²）。
在恒定加速度下，物體的運動可用以下公式描述：
