if earth's radius were bigger then how would my weight be different?

If the Earth's radius were bigger, and the mass of it stayed the same, then you would weigh lighter.  That's because with a bigger radius, you're farther away from the centre of gravity, therefore less pull.  If the mass change, then the situation would be different.

It's about 1/6 earth gravity. (But don't forget to add in 1/6 of the spacesuit you have to wear, too.)

Well, the weight of an object is inversely proportional to the distance sqaured.  According to Newton's Law of Graviation, F = (G * m1 * m2) / (r^2), in order to cut the force (or someone's weight) in half, the distance has to increase by the square root of 2, or 1.41ish.  Earth's radius is 3963 miles, so 1.41 times that is 5604 miles.  But that's the distance away from the core.  To get the altitude, subtract earth's radius.  You get an answer of 1641 miles above Earth's surface.  Hope this helped!

Gravity is determined by only 2 things- The mass of an object, and the distance that you are from the center of that mass.  So, the increased size of a planet will put you (on the surface) farther from the center of the planet, and thus decrease the gravity-but the increased mass of the planet will cause increased gravity, and the mass is by far the stronger effect.  You have a gravity strength of 1G on the surface of the Earth, for example-but if you had a planet with the same *mass* as Earth, but the size of the moon, the gravity on the surface would be much greater, because you would be closer to the center of the planet. Just those two things-the mass of the planet, and the distance on the surface between you and the center of the planet.

They have equal mass because mass does not change depening on where you are the weight would change because weight is a force and is dependent on gravity which in space would be less than on the earth.

Due to Newton's Law of Gravitational Force (see link), as the distance between two objects decreases, the gravitational force will increase exponentially.  \n\nIt all depends on your position in reference to the center of mass.  If you are on the surface of the earth, your distance from the earth is normally defined as the distance from you to the center of the earth, or center of mass.  \n\nAs you get closer to the center though, the force due to gravity changes differentially since your position in the mass itself is changing and gravitational forces are acting on you from various directions (the earth can be thought of as a sum of different aggregate masses at this point).  Therefore, the gravitational force of the earth will be "less" at the center, since the sum of all aggregate forces would be acting in opposition of each other.  However, since gravity is a relatively weak force, it would not be your biggest concern, because, at the center of the earth, it's not the force of gravity on you that matters, it's the pressure and temperature that will kill you.\n\nMagnetic and gravitational forces are completely separate types of forces and should not be considered in the formulation of this answer.

for the earth to get closer to the sun, the sun would have to grow or somehow become heavier

No, because conservation of momentum means the earth is a closed system. Plus, the earth weighs 5.972 sextillion metric tons (5,972 followed by 18 zeros)\n\nThe total earth population is currently 6,522,008,632. So assuming the whole world's population stood on one side ot the world and they were all typical Americans and weighed an averaged140kg each, the total human weight would come to 913081208480kg or approx 913,081,208 metric tons or roughly a giga ton (I forgot to include some of the larger than average Americans in my averages anyway) so the earth weighs approximately 5.972*10^9 times as much. Basically, you got more chance of propelling yourself to Mars by squeezing a zit on your face (even if your a really spotty teenager) than us all jumping and knocking the earth off orbit. \n\nHowever, if you got all those yanks to throw down a days worth of Big Macs at once, you might actually do it.\n\nDoesn't this make you feel really puny and immaterial to the world? Just be grateful you don't live on a gas giant.

The Earth is not a perfect sphere so you are at different distances from the centre at different places.\nThe density of the Earth is not constant so above dense rocks you appear slightly heavier.\nThe Earth spins so at the equator you are lifted slightly by the Eotovos effect.

hey this is a very good question. \nthe circumference divided by 24 (i.e. hours) = angular velocity travelled in one hour. \nif the rotation changes suddenly or  it stops rotating suddenly then due to the inertia that every moving object carries will suddenly travel in the direction of rotation at exactly the angular speed of the earth. so ocean water will move all over the earth and the plates beneath the earth will shift causing severe earthquakes and the volcano will erupt from the gaps due the internal pressure. so all the movable objects will shoot. these objects will move in the direction perpendicular to the centre of the globe in the direction of the motion respectively. there after stopping , there would be more gravitational force exerting on the objects cause the earth while in motion , objects have centrifugal force that is why the weight is different at the time when earth stops rotating and due to the absence of the centrifugal force weight would be more. there day will be 6 months and the night would also be 6 months longer like the north/south pole.

If that direction were opposite the direction of the \nearth's rotation, I think the answer is theoretically yes.\nIn reality there's not enough mass of people relative to the mass of the earth to have any effect.

Yes you do.  It is a very small difference, and would depend which side of the earth you were on regards it's orbital path around the sun, however you would actually make a difference.\n\nIf this is a question that has been put to you by your physics proffessor, then the answer is in the long run....no, because....when you land, you absorbe the energy you displaced upon leaving.\n\nThis is about gravity.  Look up Kepler's Law.\n\ngood luck.

Gravity is the force that holds everything down. Gravity also affects different people depending on their body mass. It you are taller, you have a greater gravitational pull on you which makes you weigh more.  The force of gravity is strongest when it is closest to the core of the Earth. The closest that we can get to the core of the Earth is sea level. So you would weigh more at sea level than you would on a top of the mountain. You would still have the same body mass, but just a different body weight. Mass is how much matter is in something, and weight is the measure of the gravitational pull on you. So that is how you can weigh a lot if you are taller. You're not fat, you just have a strong gravitational pull.

Assuming the population of the earth is 6 billion, and the average person weighs 70kg, that equates to 420 million tonnes (if I've done my maths correctly). If everyone stood on one side and jumped simultaneously, then nothing will happen as no weight would be lost from the earth.\n\nIf everyone had such springy powerful feet that they were able to jump to escape velocity (25000 mph) which means they won't come back down again, then that would cause a displacement in weight which would affect the earth.

the reaction of gravity is movement, if the object is bigger than earth then it will attract earth and earth will react

It is not effected to any significant degree.\n\nThe numbers used to do any calculations would absorb any effect which may occur.  For instance the mass of the Earth is about 5.9742 E24 kg.  But do you really think this is an exact number, no, it is just an estimate rounded off.  To try to use this value for the Earth's mass to try to calculate the effects of something so insignificant will not work too well.\n\nWhen you are standing on the Earth, you and the Earth together have a certain angular momentum.  When you jump, angular momentum must be conserved (its the law).  But now that your mass is rotating slightly farther out than it used to be, your angular momentum changes, there for the Earth's must change ever so slightly to compensate.\n\nIf you wanted "numbers and calculations", you did not specificy nearly enough information.
