When calculating weights away from Earth's surface, for example:
At 6.38x10^3 km away from Earth's surface a spacecraft s weight is d=rE+rE or 2rE
Then F=(1/4)(SpaceCraftWeight)
What I don't understand is why the distance is rE+rE?
Or when 1.28x10^4 km away
d=rE+2rE or 3rE ?
I'm also assuming since F=mAmB/d^2
That's why F= (1/(x^2)(W) ?
The weight of an object on Earth's surface is its mass multiplied by the force of gravity. In space, there is no force of gravity acting on the object, so its weight is essentially zero.
Yes, an object's weight will change depending on its location on Earth's surface. This is because the force of gravity is not uniform across the entire surface of the Earth. It is strongest at the poles and weakest at the equator.
Weight is a measure of the force of gravity acting on an object, while mass is a measure of the amount of matter in an object. Weight can change depending on the force of gravity, but mass remains constant.
No, an object cannot have weight without having mass. Weight is a product of an object's mass and the force of gravity acting on it. Without mass, there can be no weight.
Weightlessness occurs when an object is in freefall or when the force of gravity acting on the object is essentially zero. This can happen in space or during a freefall on Earth, such as in an elevator or during skydiving.
