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.
If you plug all of these values in and solve for M1, you find that the mass of the Earth is 6,000,000,000, 000,000,000,000,000 kilograms (6 x 10 24 kilograms, or 1.3 x 10 25 pounds). It is more proper to ask about mass rather than weight because weight is a force that requires a gravitational field to determine. You can take a bowling ball and weigh it on the Earth and on the moon. The weight on the moon will be one-sixth that on the Earth, but the amount of mass is the same in both places. To weigh the Earth, we would need to know in which object's gravitational field we want to calculate the weight.
