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
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.
