To improve the investigation studying the effect of gravity on objects, the student should focus on a factor that minimizes other variables affecting the drop. The appropriate way to enhance the investigation would be:

by dropping the balls from the same height.

This option ensures that the only variable changing is the mass of the balls, allowing a clearer observation of how gravity influences their fall.
