In this issue we want to talk about jokes about children who are new to math. Give the children a test on “one kilogram”. The weight of iron, 1 kilogram. Based on the question “Is cotton heavy?”, you start to say “one kilogram of cotton may be heavier than one kilogram of iron”…
Of course, under normal conditions, deviations other than the weight of the object being measured will not change the measurement results. This question involves testing children based on their daily use of iron and cotton, and it is worth noting the word “one kilogram”. However, if we deviate from the usual conditions and try to measure one kilogram of cotton per month and one kilogram of iron per earth, what will the result be?
Gravity is the primary force of nature that produces an attractive force between objects with mass. The force of attraction between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them. This law, long established by Newton, explains many phenomena, from the motion of the planets to the fall of an apple. The weight of an object is expressed in Newtonian terms, measured by its mass multiplied by its mass. Earth’s gravity is expressed as approximately 9.8 meters divided by the second squared.
Due to its mass and size, the Moon has an incredibly strong gravitational pull. This drag keeps the atmosphere and oceans in place, and keeps people aloft. The Moon is smaller and less massive than our planet. As a result, the Moon’s mass is about one-sixth that of the Earth. The difference in mass between the Moon and Earth has many strange consequences. For example, a person in the world who weighs 60 kilograms would lose 10 kilograms every month. The Moon’s low gravitational potential allows humans to stay higher and longer in the air. This is why walking or jumping on the Moon is so different from the rest of the world.
