The gravitational constant g is 9.807 m/s2 at sea level, but it decreases as you go up in elevation. A useful equation for this decrease
in g is g= a – bz, where z is the elevation
above sea level, a = 9.807 m/s2, and b= 3.32 x 10-6 1/s2. An astronaut "weighs" 80.0 kg at sea level. [Technically this means that
his/her mass is 80.0 kg.] Calculate this person's weight in N while floating around in the International Space Station (z = 345 km). If the
Space Station were to suddenly stop in its orbit, what gravitational acceleration would the astronaut feel immediately after the satellite
stopped moving?
The person's weight in N while floating around in the International Space Station is
691 N.
The astronaut feels a gravitational acceleration of
9.807 m/s2.
In Figure 1.2, get the specific gravity of
the following common substances.
