Part I. Use the
timing device to make two recoreds tapes, one for constant velocity and
one for an acclerating object.
Part II. Create a data table and record the distance
between 10 consecutive intervals of time fot the Constant Velocity
Calculate the velocity for each interval.
Make a graph of distance vs time.
Make a graph of velocity vs time.
Calculate the area under the graph on the v/t graph. What is that?
What does the slope of this curve tell you?
Part III. Create a data table to record data for
measuring the distance between 15 consecutive intervals of time for the
accelerating object.
Calculate the velocity for each interval.
Make a graph of distance vs time.
Make a graph of velocity vs time.
Use the graph to calcuate the accleration of the object.
Choose a formula and use it to calculate the acceleration of the object.
Calculate the area under the graph on the v/t graph. What is that?
Part IV. Make a sketch to predict the parttern of
dots on the tape for an object that is decreasing it's speed.
Part V. In words, summarize the results. Compare the
distance traveled during each time interval for an object with constant
velocity and acceleration.
Part VI. Write up your results as a lab report of a
web page.
