What is the reason for moon's circular motion around the earth?
Earth exerts a pull on the moon, which keeps it orbiting the Earth. Since the Earth is so big compared to the moon, it pulls the moon toward it. In a sense, the moon is falling towards the Earth, but since the moon is also moving forwards, it ends up going around and around the Earth.
Who found that the force that keeps the planets in orbit around the sun and the moon in orbit around the earth and also acts upon bodies falling to earth is the same?
Sir Isaac Newton
What keeps all planets in their orbits?
The simple answer is gravity. An apple is dropped and it falls towards the Earth. If you throw it, it travels away from you, but also eventually falls towards the Earth. Throw it harder and it travels further, but also eventually falls towards the Earth. Now throw it hard enough so it travels beyond the horizon, it's always falling slowly towards Earth, but by the time it's dropped a little the ground has moved away from it thanks to the curve of the Earth. So it keeps going and keeps falling. That is what's happening to the moon. It's constantly falling towards us, but won't hit for a very long time. And that is what's happening to the Earth around the Sun. And every other planet around the Sun. And the Sun around our galaxy, the Milky Way. And the Milky Way? It's floating around other galaxies.
Are astronaunts in orbit around earth really weightless?
The astronauts appear to be weightless as they are in a constant freefall, falling at the same speed as the space vehicle they are on. They are 'falling' but due to their angular speed, they are 'falling' around the earth, so don't crash into it. They still have their mass, but you can't really weigh the astronauts as any scales you try to use will read zero as the scales will also be 'falling' at the same rate.
Is the earth falling?
Yes. It is falling around the sun. Its not falling into the sun because the earth is also moving perpendicular to the force of gravity. Gravity is constantly pulling on it but at different angles so that the by the time the earth is moving in the direction the sun's gravity was pulling on it its now quarter of the way around it and the direction the sun is pulling on the earth is perpendicular that of the original state. Yes this means the astronautics are also falling."Flying is learning how to throw yourself at the ground and miss" Douglas Adams
Is earth falling in space?
That's kind of a loaded question, because the impact that the answer mayhave on you depends on what you mean by "falling".The answer is "yes", but that doesn't mean that you should imagine theEarth getting pulled down into some kind of sinister hole from which it cannever climb out."Falling" just means moving freely, without interference, under the influenceof gravity. When a bean rolls off the table, it moves freely toward the centerof the Earth under the influence of gravity, and falls to the floor. Gravity keepsthe Space Station and the Moon in orbit around theEarth, and they're bothcontinually falling around their orbits. The Earth is also continually falling ...in the orbit that it follows around the sun.
Is it true that a satellite in orbit around earthis always falling toward earth?
Yes, it is true that a satellite in orbit around Earth is constantly falling toward the planet. However, it also has a significant tangential velocity that keeps it in a continuous free-fall state, resulting in a curved path around Earth rather than a direct descent. This balance between gravitational pull and orbital speed allows the satellite to maintain its orbit.
What forces make the moon orbit around earth?
The main force that causes the moon to orbit around the Earth is gravity. The gravitational pull of the Earth keeps the moon in its orbit, while the moon's own momentum prevents it from falling into the Earth. Additionally, the gravitational pull of the moon also affects Earth's tides.
Is it correct to say that satellites stay in orbit rather than falling to Earth because they are beyond the pool of Earth's gravity?
No. Satellites ARE falling. But they are also moving "sideways", and so quickly that by the time the satellite has fallen to the Earth, the satellite has continued AROUND the Earth, and missed!
How does an elevator crash cause death?
When you are falling or hitting the ground, that is going to jolt you through you around which can cause death. Also when you hit the ground something might come apart and hit you which can also cause death.
What stops the water in oceans from falling out?
The force of gravity keeps the water in the oceans from falling out into space. Additionally, the shape of the Earth's surface, with depressions like ocean basins, also helps contain the water within the boundaries of the oceans.
How does gravity keeps the moon in orbit around earth?
The moon is falling, but since the Earth's gravitational pull is constantly acting on it, the moon keeps falling but it is moving towards the Earth so it move in an egg shaped motion.
