The Physics of ‘Sniping’ for Gold

YouTube videos show people YouTube knee-deep into rivers to search for gold flecks.

One way to look for these flecks of gold is to use the “sniping” method.

Why doesn’t the gold get washed away along with the flowing water? It seems strange to me, but I suspect it has to do with the very high density of gold.

A gold sniper would like to see how far downstream an o Tassie Boys Prospecting or Pioneer Pauly The downstream distance doesn't just YouTube on the density of the object, but also on its size.

The smaller the stuff, the greater the downstream separation between rocks and gold.

This is a great example of t YouTube ics of scale.

The physics of scale explains why large hail is so much more dangerous than small hail.

If you double the radius of a hail ball, you increase its volume by a factor of 8.

This means that larger hail can fall at greater terminal velocity before hitting your car. 4 8 4 8 two Earth around 19.3 grams i">Earth about 2.7 grams pan> 8 R3 R. 2R third Fg Rhett AllainNotice second Newton two two Rhett AllainThere pan> three n class="summaryFeed_highLight First _NxlGi">0.2 Fg Text__NxlGi">two Earth ummaryFeed_highLightText__NxlGi">first 9.8 newtons per kilogram class="summaryFeed_highLightText__NxlGi">7.87 grams per cubic centimeter Rhett AllainThere Rhett AllainNotice 10 centimeters 0.1 meters per second 0.5 two second 1,000 0.001 seconds Stoke lass="summaryFeed_highLightText__NxlGi">One Rhett AllainIn Feed_highLightText__NxlGi">second Newton one about 0.89 i">10-3 kilograms per meter
