牛顿第二定律的英语原文是：Newton's second law of motion.
具体来说，其原文表述为："The force required to cause a body to accelerate in a given direction is directly proportional to the mass of the body multiplied by the acceleration desired."
即力使物体在特定方向上产生加速度，该力的大小与物体质量成正比，与所需加速度的大小成正比。
牛顿第二定律的英语原文为：F=ma，其中F代表物体所受的外力，m代表物体的质量，a代表物体的加速度。
Q: What is the acceleration of a 1kg object that is pushed with a force of 2N?
A: According to Newton's second law, F=ma, the acceleration of a 1kg object pushed with a force of 2N would be a=F/m=2N/1kg=2m/s^2.
希望这个例子能帮助你理解牛顿第二定律。
