Question

Think about constructing a rational measurement system,In devising this measurement system, you must choose two “universal constants” that you will use as the basis for your system (such as the speed of light and the mass of an electron, for example). Now, imagine that you want to conduct an experiment that will allow you to accurately measure a third quantity, using the two universal constants you selected, such as the free fall time of an object dropped from a building, or the length a cannonball travels when fired at an angle. Apply the scientific method to ask the question, "How far will the cannonball fly?" and use your measurement system to record the distance. Including the following :

Which difficulties would arise for them in confirming or denying the validity of your results?

What are the control variables in your experiment?

Which other measurements would you need to devise to monitor them?
