WebValue of g is calculated as −. g = G M R 2. G = universal gravitational constant, which is = 6.7 × 10–11 N m2 kg-2. M = mass of the earth, which is = 6 × 1024 kg. R = radius of the earth, which is = 6.4 × 106 m. So, g = 6.7 × 10 − 11 N m 2 k g − 2 × 6 × 10 24 k g ( 6.4 × 10 6 m) 2. = 9.8 m s − 2. So, the value of acceleration ... WebThe centimetre–gram–second system of units (abbreviated CGS or cgs) is a variant of the metric system based on the centimetre as the unit of length, the gram as the unit of mass, and the second as the unit of time.All CGS mechanical units are unambiguously derived from these three base units, but there are several different ways in which the CGS …

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.

Center of Gravity (CG) of an object is a point at which the entire weight (Force) of an object considered to be concentrated.It is the geometric property of any object. CG is the point at which weight is evenly dispersed and all sides are in balance. If the CG of an object is exactly known, then one can balance the object on a pinpoint at this … WebHans Geiger.
