The velocity can be determined once the orbital period is known (see
Last Step) Velocity is defined as the distance an object
travels divided by time. For a circular path, the distance traveled
is the circumference, 2pr.
Where "r"
is the distance the satellite is from the center of Earth. Determine
the velocity, v ; be sure you carefully specify your units.
|
orbital velocity v = (2p r) / t where "t" is orbital period |
distance from center of Earth r = Eradius + Hheight where "Eradius" = 3960 X 103 m |
Determine the orbital velocity of the Yohkoh spacecraft.
