Why is the law of universal gravitation important?

Brave001 it's not important .. we physisct are not rasict that we have favourite laws.. it is actually the most fundamental laws of physics which actually binds the whole galaxies and gases .. frankly speaking we have many misconceptions and unknown facts ..and we still don't know what gravity is and about its origin. that what makes them to call important.. it is equally important as any other theorem or law .. after all it's mother nature who is behind it .

The chemical reactions lab we did is typically called a "copper plating lab,  because the acid solution cleaned the pennies and made the copper look shinier;   the acid solution cleaned the paperclips and made them look like pennies;   &   the copper from the pennies was removed, and then added to the paperclips.
