Is Weight constant every place in the universe?

Answer 1

No, the earth has a greater pull on a body at the poles, making anything slightly more heavy there. This is for two reason: 1) Because of the shape of the earth, (a slightly flattend sphere) the distance to the core of the planet is greater at the equator and lesser at the poles. Thus, the gravity is greater at the poles. 2) Imagine the earth as a sphere on a vertical stick, spinning really fast. Its not hard to imagine things on the equator being slingshotted away from the earth, while at the top and bottom of the sphere there is no such effect. In reality, ofcourse there is not nearly enough speed for anything to be slingshotted off the earth, but the effect remains in tiny amount, pushing bodies slightly away from the core, and thus creating the effect of decreased weight.

Answer 2

no it depends on gravity. A good example to illustrate this is that the 'big arm' that you sometimes see on TV sticking out of the space shuttle cannot lift its own weight on earth but because it weights alot less in space due to gravity, it is designed to move in space under its own weight with no problems.

Answer 3

No. Weight is technically measured in newton's, which is the unit of force. To solve for force. you multiply an object's mass by the acceleration of gravity (F=ma). Although an object's mass is constant, the acceleration of gravity is slightly different on different places on the planet, so as acceleration of gravity changes, weight changes.

Answer 4

No, weight is not constant throughout the universe. Weight is a force that depends on an object's mass and the acceleration due to gravity. Since gravity can vary in different locations in the universe, an object's weight can change depending on its location.
