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....

time graph for the car trip The velocity versus time (or v vs. t) graph shows velocity on the vertical axis and time on the horizontal axis. This graphical model provides a quick visual history of how the velocity changes. The v vs. t graph can fool you, however, unless you remember...
The example of the "clock paradox" is discussed and a complete resolution is obtained by giving an exhaustive unified description of all possible situations. Velocity (and nothing else) is thus seen to be responsible for the differential retardation effect....
Now it is time to re-create the distance equation in Equation 5-1. The first step is to calculate the differences between the second and first x and y points: var dx = p2.x - p1.x; var dy = p2.y - p1.y; To determine the distance, we square both the values we just create...
In this Review, we disentangle the respective roles of the arrow of time and the non-Boltzmann nature of steady-state fluctuations in this rich phenomenology. We show that effective, time-reversible descriptions of active systems may be found at all scales and discuss how interactions, either ...
