Question

I need help with coming up with a conclusion for this experiment. In this lab, we measured the value of the acceleration gravity has on different sizes and masses. The objective of this lab is to see if mass affects the accerlarion of the objects. How should my conclusion be?

Thanks

Explanation / Answer

As you can see equations of different graphs are given in the form

Y = mX + C where m = slope = acceleration due to gravity of the material.

According to ideal conditions all m should be same.

but here all are different. this could be justified by taking the effect of air resistence into account.

Air resistence is the force which depands upon shape, size and density of the object.
