Given the constant rate at which velocity changes, initial velocity, and time duration, how do we reason out the corresponding change in the position of an object? multiply velocity by the time duration to get the change in position
How do we determine position changes over specified time intervals from a graph of velocity vs. clock time, and how can we then construct a graph of position vs. clock time?
determine the area of the trapezoid under the lenght of the graph you wish to find the position change of. You can then plot these values on a graph of position vs. clock time.
In terms of the meanings of altitudes, area and width, how does a velocity vs. clock time trapezoid represent change in position?
avg Altitude multiplied by width gives you area, which is equal to the change in position during that clock time.
How can a series of velocity vs. clock time trapezoids help us to calculate and visualize position vs. clock time information?
They allow us to visualize the changes by giving us lines to relate the information to. They also allow us to calculate any value desired from simple measurements and multiplication."
