Question

In our lab experiment, we used units of mass on force quantities. In most cases this would be considered incorrect and would lead to incorrect results. Why were we able to do this in this experiment? Show an example calculation that indicates the use of correct units and demonstrates why this was not necessary for these computations.
I know that F= ma. In this case, a is gravity. m x g will equal the weight. Why was I able to keep mass units and still be correct? How can I prove that it is correct in this case in equation form?

Explanation / Answer

the multiplying factor is same for all the forces so it can be substituted by mass instead of force and whatever formulae we used comprise of ratios of the forces so that the common multiplying factors cancels out giving us no wrong ans .
