Explain the relationships between instantaneous velocity, average velocity, instantaneous speed, average speed, displacement, and time. Calculate velocity and speed given initial position, initial time, final position, and final time. Derive a graph of velocity vs. time given a graph of position vs....
Velocity-time graphs are essential for analyzing motion, where the y-axisrepresents velocity and the x-axis represents time. The slope of these graphs indicates acceleration, with steeper slopes signifying greater acceleration magnitudes. Average acceleration is calculated between two points, while i...

velocityAtTime,speedAtTime和valueAtTime完整地写应该是：velocityAtTime(t),speedAtTime(t)和valueAtTime(t)。意思是返回t那个时间的velocity、speed和value的值，这个t的时间单位是秒。比如：valueAtTime(5)，那就是返回5秒的时候这个参数的value值。

We assume that the proper time along each short space–time segment of the path may be calculated treating each sufficiently small segment of the world-line as a straight line, and we calculate the proper time assuming the clock moves with constant velocity along each short segment. The proper...
However, the SV equation—as a simulation model inside the model predictive control mode (MPC)—has a long calculation time and slow speed, which cannot meet the rapid simulation requirements of automatic control algorithms. Therefore, this study used the integral delay (ID) model instead of the...
