加速度

三个质点从坐标原点以相同的速度出发,由于分别拥有正、零、负的加速度而导致其位置和关于时间的曲线。
用两次差分表示如何从位移矢量近似地得到加速度矢量,在数学表示中以粗体或是上方标注箭号为矢量。
加速度按自然坐标系分解
在这篇文章内,矢量与标量分别用粗体与斜体显示。例如,位置矢量通常用\mathbf{r}\,\!表示;而其大小则用r\,\!来表示。

加速度是物理学中的一个物理量,是一个矢量,主要应用于经典物理当中,一般用字母\mathbf{a}表示,在国际单位制中的单位为米每二次方秒(\mathrm{m/s^2})。加速度是速度矢量对于时间的变化率,描述速度的方向和大小变化的快慢。

在经典力学中,牛顿第二定律说明了力和加速度成正比,这定律又称为「加速度定律」。假设施加于物体的净外力为零,则加速度为零,速度为常数,由于动量是质量与速度的乘积,所以动量守恒。在电动力学里,呈加速度运动的带电粒子会发射电磁辐射。

Acceleration 加速度

Kinematic quantities of a classical particle: mass m, position r, velocity v, acceleration a.
Acceleration is the rate of change of velocity. At any point on a trajectory, the magnitude of the acceleration is given by the rate of change of velocity in both magnitude and direction at that point. The true acceleration at time t is found in the limit as time interval Δt → 0 of Δv/Δt
From bottom to top: an acceleration function a(t);the integral of the acceleration is the velocity function v(t);and the integral of the velocity is the distance function s(t).

Acceleration, in physics, is the rate of change of velocity of an object. An object's acceleration is the net result of any and all forces acting on the object, as described by Newton's Second Law. The SI unit for acceleration is metre per second squared (m s). Accelerations are vector quantities (they have magnitude and direction) and add according to the parallelogram law. As a vector, the calculated net force is equal to the product of the object's mass (a scalar quantity) and its acceleration.
