How do we reason out the process of determining acceleration from rest given displacement and time duration? You can find acceleration by taking the displacement divided by the time duration which equals the average velocity. You then take the average velocity and divide it by the time duration and you have the average acceler
You have to divide changes in the ave velocities by the corresponding changes in clock time.
How do we obtain an approximate velocity vs. clock time table and graph from a series of position vs. clock time observations? How do we then obtain an approximate acceleration vs. clock time table and graph?
By calculating the time interval and displacement between each successive pair of data points, and use this to calculate the average velocity over each time interval. Now you can plot the velocity vs time graph you can then take the slope of this graph and this is the acceleration.
For water flowing from a uniform cylinder through a hole in the bottom, with how much certainty can we infer that the acceleration of the water surface is uniform?
By making a graph of the information we can be more certain of the information. If the graph of velocity vs time is linear then you can be certain that the acceleration is constant.
