Miles Per Hour with Toy Cars (Converting Units w/ Dimensional Analysis)

How Fast is a Toy Car Really Traveling?

To examine this question and teach dimensional analysis we converted feet per second to miles per hour using a toy car.

Step 1: Using a stop watch, yard stick and a windup toy car we calculated the average feet per second to be



Step 2: We set up the problem


Step 3: We used conversion techniques to translate ft/sec to miles/hour.     


This little car was traveling approximately 2.26 miles/hour
