它的二阶导数就是这个恒加速度。
研究恒加速度过阻尼动圈式地震检波器参数的测量方法。
It focuses on parameter measurement for constant acceleration overdamped coil type geophones.
就是众所周知的恒加速度的速度方程。这个方程是线性的,这条直线的斜率就是加速度。
Is the well-known equation for velocity under constant acceleration. This equation is linear; the slope of the line is the acceleration.
So, the question we are going to ask is the following, "If I tell you that a particle has a constant acceleration a, can you tell me what the position x is?"
接下来要问的问题就是,如果我说某质点加速度恒为a,你能告诉我它的位移x是多少吗
