          Collecting data

          Here are some students determining the angle in which the racer overcomes starting friction.

          The idea is to establish a baseline (control) then vary one parameter. 

          First port of call is are the wheels too wide.

          The chasis are made from core flute, of which there is plenty to be had 

          • at drive in bottle shops
          • political elections etc

          Smarty pants know

          sinΘ = opposite side/hypotenuse

          and you can get the the angle by

          asinΘ of sinθ

          The drain pipe is 1m long therefore the measured side in cm is the vlua of sine

          so the asin of the boys' measurement, 300 mm or .3m is 

          asin .3 = 17.45 degrees.
