Does weight of an object chance in uniform upwmotionard motion

As the ratio between present gravitational force to initial gravitational force.
If we call r the initial distance from the center of the Earth, r+vt (where v is the velocity you move away with), you should be able to calculate for yourself that ratio of weights, as a function of time.

 

Do you think it would increase or decrease when you move away from the Earth?

 

Since you used the colloquial definition of weight, a synonym for mass, the answer is simple: It "weighs" 10 kg, anywhere and everywhere.

That colloquial meaning is not what physicists and engineers mean they talk about "weight". Physicists use the word "mass" to denote mass. Why use the word "weight" when there is already a perfectly good word for mass? Weight in physics has units of force in physics. There are two widely used definitions: The force due to gravitation on the object (mass times gravitational acceleration), and the total of all forces acting on the object except for gravitation.

What arildno is hinting at is mass times acceleration, or Newton's universal law of gravitation. What does that have to say about the force due to gravitation as altitude increases?

 

Then why did you persist in saying the weight is 10 kg? Kilograms are a unit of mass, not force.

That is not the definition of weight used in general relativity (your next post, below). In general relativity, "weight" is what an ideal (spring) scale measures. That's all real forces except gravitation (Newtonian interpretation), or all real forces, period (general relativistic interpretation). Gravitation is not a real force in general relativity.

Where did you get this idea?

 

10kg. You must accelerate or de-accelerate for the scale reading to change. You can test this in an elevator. Scale reading will change at the beginning and end of the ride.
