Where the gravitational pull of earth exists up to?
The gravitational pull decreases in inverse proportion to the square of distance from the centre of the earth, thus it would speedily decrease as we go away from earth but never become zero anywhere, it remains, in however small quantities. Say, 160 km from the surface of the earth, the gravitational pull would be 0.95 times that at the surface of the earth (which is 9.81 m/s2). At 400 km from the earth (where the International Space Station seems to be floating), it would be 0.88 times that which is at the surface of the earth. Near moon, it would be .000272 times of what we feel here. Now, the weightlessness they feel on the International Space Station is due to the fact that the Space Station is circling around earth once in 91 minutes. The centrifugal force compensates for the remaining 0.88 g gravity there.
What two ways the sun holds earth in orbit because of?
There are two factors at play when we are looking at satellites orbiting around another object. The same applies for a man made satellite in orbit around earth or another planet, a moon (natural satellite) in orbit around a planet, or the planets themselves orbiting around the sun. There is the satellites the tangential velocity acting away from the system and the gravitational attracting keeping the bodies close together. The satellites have a tangential velocity, they are speeding along sideways relative to the Earth (for example). If there was no gravity, this velocity would take the satellite away from the Earth, but the Earth has a gravitational force which counteracts this effect. The Earths gravitational force is constantly attracting the satellites in, against this tangential velocity. If the satellites were to slow down, then they would eventually spiral into the Earth, but in orbit there is very little drag, so the satellites pretty much maintain their speed and their orbits, though they do need a boost occasionally to keep them in orbit due to the small amount of atmospheric drag over time.
Is the gravitational potential of the earth equal to that of the moon at the point between earth and moon where the resultant gravitational potential is maximum?
Potential energy is the energy stored in a body or in a system due to its position in a force field or due to its configuration.Orbit is the gravitationally curved path of one object around a point or another body, for example the gravitational orbit of a planet around a star.A "point" is an abstract concept, it's infinitely small and has no mass. A real object would have mass and create a gravitational field on it's own, regardless of whether or not it was inside a hollow sphere. We have to observe circular motion and Linear velocity. Potential energy is energy that is stored within a system. It exists when there is a force that tends to pull an object back towards some lower energy position.According to the law of conservation of energy, energy cannot be created or destroyed; hence this energy cannot disappear. Now we have...Gravitational energy whcih is the potential energy associated with gravitational force.Hence the moon is smaller than the Earth, combining these reasonings, the moon will never have a gravitional potencial equal to the Earth.
Does the mass of an astronaut change when he or she is visiting the international space station?
The force of gravity decreases with the distance between bodies, but it is still about 90% of the sea level value in high Earth orbit. There zero gravity exists because of the "free fall" of the orbit. At some point several thousand miles from Earth, the attraction from the Earth or the Moon does become very small, creating virtual weightlessness.Gravity is inversely proportional to the distance from the center of mass, which is why on the Earth's surface the effect of the Sun's gravity (which is much greater) is negligible compared to that of the Earth.
How is input force used?
Since we know by conservation of energy that no machine can output more energy than was put into it, the ideal case is represented by a machine in which the output energy is equal to the input energy. For simple geometries in which the forces are in the direction of the motion, we can characterize the ideal machine in terms of the work done as follows: Ideal Machine: Energy input = Energy outputWork input = Fedinput = Frdoutput = Work output From this perspective it becomes evident that a simple machine may multiply force. That is, a small input force can accomplish a task requiring a large output force. But the constraint is that the small input force must be exerted through a larger distance so that the work input is equal to the work output. You are trading a small force acting through a large distance for a large force acting through a small distance. This is the nature of all the simple machines above as they are shown. Of course it is also possible to trade a large input force through a small distance for a small output force acting through a large distance. This is also useful if what you want to achieve is a higher velocity. Many machines operate in this way. The expressions for the ideal mechanical advantages of these simple machines were obtained by determining what forces are required to produce equilibrium, since to move the machine in the desired direction you must first produce equilibrium and then add to the input force to cause motion. Both forceequilibrium and torque equilibrium are applied.
Can you create gravitational force?
Gravitational force is the attraction between two masses. It can be explained by Force=(Mass1*Mass2)/Distance. Everything is attracted to the earth because the earth has such a large mass. So on a small scale it is just about impossible to create gravitational force.
How can the sun have a large gravitational affect on earth but a small gravitational force on you?
The gravitational force between two objects is proportional to the product of their masses. (sun's mass) times (earth's mass) is a very large number. (sun's mass) times (my mass) is a much smaller number.

How does the sun have a large gravitational force on earth but a small gravitational force people?
Look at the formula for gravitational force. It depends on BOTH masses - as well as the distance. In this case, Earth has a large mass, people have a small mass.Also, people just "move along" with Earth - if the Sun pulls on Earth and on us, we accelerate TOGETHER towards the Sun.
Gravity is a force which?
Every object has a (small) gravitational force that attracts other objects. The proportion of the Earth - human is so large that we sense this attraction force of the Earth. Gravity is the force which makes our feet stick to the ground!
What is the gravitational force of the planet pulling on the sun causes?
The gravitational force from a planet on the sun is so small. For example, 1,000,000 Earths can fit in the sun. The mass of the sun is 333,000 times bigger than the Earth. It is the same way you on Earth. You have a gravitational force on the Earth but it is so small.
What are the 4 types of Mechanical force?
Gravitational, Electromagnetic, Small nuclear, and Large nuclear force..
Where earth gravitationl force become zero?
Because there is no range limit on the gravitational force, the gravitational force of the earth is only zero in the exact centre of the earth, where it cancels itself out. Realistically, the force is so small outside the immediate vicinity of earth, that it may as well be zero.
How does an object exert gravitational force on every other object?
Because every body no matter how small has mass. We don't notice the gravitational force between the people and things around us because the mass of the earth is so large in comparison.
Why are objects on earth not attracted to the two poles of the earth?
That is not correct.Objects on Earth are attracted to Earth, AND they are attracted to one another. The magnitude of their attraction to one another is usually quite small, due to their small size.
Only the earth exerts gravitional force on all object is it true?
Anything with mass include you and me do exert gravitational force but the earth is massive so it exert more force than any of any small object including us on earth. The gravitational force is done between two mass in following general gravitational law by Newton. F = G.M1m2/R2 We sum up G.M1/R2 as gravity = 9.81 m/s2 for M1 is earth and R = earth radius Between 2 man with m1 and m2 respectively, gravitational force between these two man is at F = G.m1m2/L2 where L = distance between center of mass (you and me for instance). Gravitational force is small compare to earth's gravitational force but it does exist.
why we can not feel gravitational force around us?
The masses of humans are quite small and thus the magnitude of gravitational force is also very small and negligible as compared to that shown by Earth. Thus, gravitational force exists between two people sitting close by but it is negligible and cannot be felt.
