Summarize at least three steps needed to carry out Galileo's famous experiment to determine whether heavier objects
LenaWriter [7]

Answer:

Explanation:

According to legend, Galileo dropped weights off of the Leaning Tower of Pisa, showing that gravity causes objects of different masses to fall with the same acceleration. In recent years, researchers have taken to replicating this test in a way that the Italian scientist probably never envisioned — by dropping atoms. One of Galileo's contributions to the founding of modern science was his study of falling objects.  He turned, then, to measuring the acceleration of objects rolling down smooth ramps. The ramp "diluted" the acceleration to a value small enough to allow accurate measurements of the longer time intervals.
