With gravity? ,

How does rotation of a body affect its gravity, which is caused by mass alone..

...

Firstly, when a satellite is in orbit around the earth, gravity is considered to be a centripetal force.

But when a satellite is still on the earth's surface

Code: Select all

dim as double N 'normal force on satellite to be calculated.

dim as double g 'acceleration due gravity

dim as double v 'velocity of the earth's surface at the equator

dim as double r 'radius of earth

dim as double m 'apparent mass of a small satellite at a pole.

g=9.81 'm/s/s

v=460 'm/s

m=80 'kg

r= 6378e3 'm

N = m*g-m*(v^2/r) 'newtons (via centripetal force at equator).

print "Apparent mass of a small satellite at the North Pole "; m

print "Apparent mass of a small satellite on the equator ";N/g

sleep

I say apparent mass because there will also be a buoyancy factor, but it will be nearly the same at equator and pole.

We use the term gravity for various calculations, but we don't truly know what gravity is.

Which is why Albert is trying to get to the bottom of it all via a medium of ether.
