INVESTIGATIVE QUESTION: To Be Determined (By your group) but it MUST include acceleration data


We measure acceleration in much the same way that we measure velocity. That is to say that velocity is a measure of the change of an object's displacement over time and acceleration is a measure of the change of velocity over time.

Recall that average velocity is measured:

(df - di)/(tf- ti)

  • where d stands for displacement and t stands for time

We measure average acceleration in a very similar way:

(vf - vi)/(tf - ti)

  • where v stands for velocity and t stands for time



The purpose of this lab is to collect data to determine the average acceleration of vehicles starting from rest at the 4-way stop down the street and associate that with some other observable factor.

That is by way of saying you MUST tie that acceleration into some other factor (a simple factor would be by gender of driver. Since I just suggested that, you can't use gender <sorry>).


I have two radar guns that give instantaneous velocity.

Please keep in mind I only have two radar guns. Detective Mike Allen from GHPD will train us on the proper use of radar guns the day before we head out to Rosedale to actually take the data.

We have 6 or 7 groups per class so SHARING is a must.

STEP #1: Work with your group to develop some sort of interesting, provocative or otherwise illustrative lab that centers on the measured acceleration of vehicles away from the stoplight on Rosedale (in front of GHHS).

You have wide latitude on this. The more your lab moves away from predictable and boring, the more interested your MG&HPI will be.

STEP #2: Determine a method for determining displacement, velocity and acceleration using meter sticks, chalk and stop watches or some other method. This will be your fallback method in case your group is NOT selected to use radar guns.

STEP #3: Detective Mike Allen from the Gig Harbor PD will join us next Wednesday, October 2rd, 2019 to instruct us on proper use of radar guns. Please be prepared with questions, comments and concerns

STEP #4: Begin Prelab. Make sure to deal with the pesky concept of "control variables".

In any lab investigation we try to keep every possible parameter of that lab the same.... EXCEPT that one thing we are investigation (the Manipulated or Independent Variable).

For example, if we were conducting an investigation to find out which of our personal cars got the best gas mileage, we would need to "Control" for various factors.... let's discuss.
