Decentralization, on the other hand, refers to the extent to which authority has been passed down to the individual school. Site-based management is an example of decentralization in which individual schools can make their own decisions related to finances and curriculum.
Mass and weight example - the moon. In the below example, we've featured an astronaut on earth and on the moon. The Moon's gravity is much less than the Earth's gravity - approximately one sixth. So, a 100 kg astronaut weighs 980N on Earth. On the Moon, the astronaut would weigh only 162.2N. However, the astronaut's mass is 100kg where-ever they are. Weight on Earth: 100kg x 9.8m/s2 = 980N. Weight on Moon: 100kg x 1.622 m/s2 = 162.2N.
Earth has a mean density of 5.5 grams/cubic centimeter, but the moon has a density of only 3.3 g/cc. The reason is the same, that the moon lacks iron. The moon has exactly the same oxygen isotope composition as the Earth, whereas Mars rocks and meteorites from other parts of the solar system have different oxygen isotope compositions.
