WebWhat is interesting about gravitational potential energy is that the zero is chosen arbitrarily. In other words, we are free to choose any vertical level as the location where h = 0 h=0 h = 0 h, equals, 0.For simple mechanics problems, a convenient zero point would be at the floor of the laboratory or at the surface of a table. WebAn erg is the amount of work done by a force of one dyne exerted for a distance of one centimetre. In the CGS base units, it is equal to one gram centimetre-squared per second -squared (g⋅cm 2 /s 2 ). It is thus equal to 10 −7 joules or 100 nanojoules ( nJ) in SI units. 1 erg = 10−7 J = 100 nJ. 1 erg = 10−10 sn⋅m = 100 psn⋅m = 100 ...
