What the relationship between earths self rotation speed and human population?
OK. I agree with the others, but if your teacher wants to push the issue, here is an answer. Conservation of Angular Momentum says that if we increase the mass at the edge of a spinning circle (circumference of the earth) the rate of rotation slows down. So, lets take that and run with it. Can we increase the mass at the surface of the earth? Classical Physics: No. Conservation of mass says that the total mass of the earth is a constant ===> Any mass that came from an increase of human beings (living things) must come from non-living things ===> Mass at the surface of the earth cannot increase ===> No effect Relativity: Yes, But the difference is insignificant: Living things get energy from the sun, directly and indirectly, that energy is converted to living tissue ===> Mass of living tissue increases according to E = Mc^2. Figure it out for all of the time things have lived on the earth and you get a mass increase that probably cannot be measured (I did NOT try to figure it out, but I
There is no correlation between the two. The human population is of no significance when compared to any mass or distribution of mass that could affect the rate of turn of the planet. There is an extreme bimodal link. If the planets spin was so great that its self gravitation was unable to hold the planet together, then this would have a dramatic affect on the population. And even slower speeds could shuck off the atmosphere . And very low speeds would result in massive temperature fluctuations that would limit the human population a lot…. so there is a link between the rotation rate of the planet and human population. But not in the reverse – the human population does not, cannot , affect the rotation speed of the planet.
