How can you derive the formula for the apparent weight at any latitude on the Earth?
My textbook derives the formula for apparent weight at the equator, which is just equating the centripetal force to the difference between the true weight and normal reaction.
$$ mg' = mg + m \omega^2 ...

What happens to your weight when you go a specific height above the surface of the earth?
How would you use the Universal Gravitation equation $F=\frac{Gm_1m_2}{r^2}$ to calculate the weight of a person at a specific height above the earth?
If, for example, you were 6370m above the earth ...

Confused by gravity and weight [closed]
I know that $F = mg$ so $2,00 \textrm{ KG m} \cdot 9,81 \textrm{ N g} = 19,62 \textrm{ N F}$
Why does my book say that the weight of a $2,00 \textrm{ KG}$ object is $19,62\textrm{ N}$, the mass is $2,...

What is the weight of the Philae lander on the Churyumov–Gerasimenko comet compared to earth?
We know the payload mass of the Philae lander was 21kg.
We know the mass of the Churyumov–Gerasimenko comet is roughly 1 x 10^13kg.
We know the mass of Earth is roughly 5.9x10^24kg.
I've heard ...
