Physics 11: Our first lab!

Over the last week we've been learning how to work with graphs of distance vs. time, and velocity vs. time. Now it's time to try it out for ourselves. You've been given two sets of data. One is distance vs. time and the other is velocity vs. time. What I'd like you to do now is:
  1. produce a graph for each set of data
  2. from the distance vs. time graph determine the maximum velocity (slope of a tangent line), average velocity (total distance divided by total time), and total displacement.
  3. from the velocity vs. time graph determine the maximum velocity, and displacement (the area under the line).

Be sure to follow the guidelines we copied into our notes about what a good graph looks like and show your work and calculations on a separate page for each graph (If it's organized with titles it's so much easier to mark).

Also, be sure to add a paragraph or two describing the motion and what you sort of graph you should get (Theory section). Compare the data in relation to the motion you obsevered in class (not all of the data will make sense at first...explain why-Discussion section). State the values you calculate (Conclusions). Good luck.

Here is a nice site, that explains slopes from 2 different points on a line on a graph. There is an animation showing why the slopes are off.
