If you think that you have recently become a little stout and become heavier, then it's time to go to the moon. Gravity there is much less than on Earth, which means you will experience several times less weight from your own weight. Recall that weight is the product of body mass and gravity, which on the moon is only 17% of the earth. The force of gravity on the moon is 6 times less than on our green planet. It's hard to believe and pretty hard to imagine. To facilitate your task, we give a specific example.
Suppose there is a body whose weight on the earth is 100 kilograms. If you put the same object on the moon on the scales, the arrow will be thrown only up to the mark of 17 kilograms, which means that due to low gravity on the moon, you can bounce high like a ball.
Again we turn to a specific example for clarity. If on our planet you are able to jump 30 centimeters from the surface of the earth, then with the same efforts in the conditions of lunar attraction you can jump as much as 2 meters. In addition, falling on the Moon is much milder and more pleasant than on Earth. You definitely won’t feel the blow. But you can easily feel that you are flying.
How do astronauts move?
The first people who appeared on the lifeless satellite of the Earth probably did not know exactly what gravity on the moon. Therefore, when they hit the surface of the Earth’s satellite, astronauts had to jump around. If they decided to walk in the usual habitual step, they would surely fall. However, due to low gravity on the moon, each astronaut can feel himself for a short period of time as a bird that can fly. We are sure that this is an amazing and incomparable feeling that everyone would like to experience.
So, we found out whether there is gravity on the moon, so we can safely move on to another, no less interesting topic - to common misconceptions about this interesting phenomenon.
Myth 1. There is no gravity in space
Looking at the astronauts, we can assume that they are in absolute zero gravity on the international space station. This is partly true, but do not forget that in space they are also affected by the gravitational force of the Earth, which holds artificial and natural satellites. Yes, the gravitational force of the Earth is so strong that even in space it pulls toward itself.
The only difference between a single cosmonaut and a satellite is the difference in their mass. The force of gravity is directly proportional to this value, so astronauts do not fall on the surface of the Earth and in fact do not depend on this attraction.
Myth 2. The parade of planets will reduce the gravity of our planet.
A parade of planets is usually called a cosmic phenomenon, in which all the planets of the solar system line up in an even row, and their attractive forces add up. Even if we ignore the fact that such a situation is impossible, since it contradicts the laws of physics, we will pay attention to those celestial bodies that can affect gravity. Such planets are Venus and Jupiter. The first is due to its proximity, although the mass and volume of Venus are small.
The second celestial body influences the Earth’s gravity precisely due to its huge mass and volume, although it is located quite far from our planet. Using simple mathematical calculations, one can come to the following figures: the gravity of Venus affects the Earth 50 million times less, and the attraction of Jupiter is 30 million times less. Given the fact that both planets are located on opposite sides of ours, during the parade of planets they will compensate for each other's gravity, which means the gravity will not change.
Myth 3. Black holes tear objects apart
Despite the fact that black holes are still a mystery to scientists, some facts about them are still known. For this reason, we can confidently say that they in no case tear objects near themselves, however, provided that their mass is not very small by cosmic standards. It is important to understand that the power of black holes is directly proportional to their size and the dimensions of the bodies that are near them. If there is a star next to the supernova whose mass is equal to 10 masses of the sun, then it can be torn. And in the event that its mass is close to 1000 masses of the suns, then the hole can only absorb it entirely.
Despite the large number of scientific errors, in no case can not be trusted in them, you must always check any information in official and authoritative sources.
Conclusion
Based on the foregoing, it remains to be hoped that this article was useful to you, and you read it with interest to the very end. Now you know exactly the most important thing about gravity on the moon and other bodies of the solar system. We can only wish success in the further study of new and interesting facts that will help you understand how our world works.
