![]() ![]() ![]() Both objects exert an equal attractive force on each other: a falling object is attracting the Earth with the same size force as the Earth is attracting it. The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases. There is a gravitational force of attraction between every object in the universe. ![]() Gravitational forces are considered to be inherently linked to what we call ‘ mass’. there is no gravity in a spacecraft orbiting the Earth.gravity acts upwards on things that are moving upwards.It does not operate on things that are moving upwards gravity affects things while they are falling but stops when they reach the ground.gravity is caused by the Earth spinning.gravity is significantly less on high mountains or tall buildings and increases as we lose height (which is why falling objects speed up).(Hence there is no gravity on the moon, in Earth satellites or in space as one rises above the surface of the Earth gravity lessens because the atmosphere thins) gravity is related to the presence of air, or is something in the air, so if there is no air, there is no gravity.gravity is a push from above (in some instances due to air pressure).Students may have a range of views about gravity: This idea is also developed in the focus idea Students’ views about gravity, the shape of the Earth, and the direction of ‘down’ are often intertwined. Things falling towards the Earth are such familiar occurrences that students may consider these events as ‘natural’ with no need for further explanation.Įven students who use the word ‘gravity’ in an appropriate context may not be able to be able to explain what it is, or will be inconsistent in their explanations. Contrasting student and scientific viewsĬontrasting student and scientific views Student everyday experiences.Idk how we have not figured this out yet. Exactly like electrons orbiting a nucleus. EM fields propagate in the same manner, we are of course aware of them, but the magnetosphere doesn't just deflect space, it is ewhat bonds us to the sun. They are identical to magnetic field arches. It can be seen in the plasma arches on the sun. They are in vibrational grooves, like a phonograph, but imagine the needle(planet) has to fit in the right groove. The planets are held in orbit by electricity. These two planets smash gravity theory into non-existence. Why is Venus, similar in size and composition, pulled into the sun? Isn't this a necessary result of gravitational theory? As well, obviously, Mercury, how would it achieve a balance at a distance where the gravitational force is much stronger than 1au? It's also further away from the influence of the giants as well. Presuming the Earth is in an optimal orbit relative to it's mass and composition, as science and ToR tell us, and relative to gravity, or the gravitational pull of the sun at this distance away. And gravity does get weaker with distance, but there’s still enough to hold onto Pluto and things beyond it. So, between them and the space ship, there’s no acceleration.Ĭhris - Let’s take it to it’s logical conclusion the reason that Pluto is 6 billion kilometres from where we are here on Earth and it’s still orbiting the Sun is because the Sun’s gravity is hanging onto Pluto, even though it’s that far away. ![]() They’re still experiencing the Earth’s gravity but so is the spaceship that they’re in. So zero G is not distance away from the Earth.Ĭhris - So people who are on the International Space Station, the reason that they are in orbit around the Earth is because gravity is hanging onto them and keeping them in orbit? But they’re just free-falling around the Earth all the time so that they’re weightless, but that’s not the same as zero G?ĭavid - Correct. So it’s like the lift dropping down the lift shaft. Zero G in space is because you’re in a space capsule accelerating under gravity, orbiting the Earth, or going from one body to another and you’re not accelerating : the person within the spaceship is accelerating at the same rate as the vessel. If you double your distance from the centre of the Earth, the gravity would decrease to a quarter of what it is at the surface, but that’s not zero G. ![]()
