In uniform circular motion, total acceleration of an object in a circular path is equal to the radial acceleration. Due to the presence of tangential acceleration in non uniform circular motion, that does not hold true any more. To find the total acceleration of an object in non uniform circular, find the vector sum of the tangential acceleration and the radial acceleration.
Pyrite is a polymorph of marcasite, which means that it has the same chemistry, FeS 2, as marcasite; but a different structure and therefore different symmetry and crystal shapes. Pyrite is difficult to distinguish from marcasite when a lack of clear indicators exists.
Rainbow Pyrite Color Rainbow pyrite displays a shimmering rainbow of colors, including shades of gold, green, pink and blue. Pyrite crystals are normally pale-yellow, brass-yellow or gray-yellow in color, and are often tarnished with brown color owing to iron oxide.With rainbow pyrite, quality is not determined just by color, but also by the size and evenness of crystal coverage.ainbow Pyrite Color Rainbow pyrite displays a shimmering rainbow of colors, including shades of gold, green, pink and blue.
