Ellipse • Ellipse – an oval shaped curve that is the path of a point that moves such that the sum of its distances from 2 fixed points (foci) are constant • When foci are together, the ellipse is a circle. • A circle is a special case of an ellipse
Orbit • Satellite speed varies in an elliptical orbit • When the initial speed is more than 8 km/s, the satellite moves away from the earth and loses speed
Orbit • The satellite slows down and begins falling back towards earth • The speed that is lost is gained when it falls back • It then rejoins the path and repeats the same cycle
Describe an ellipse • An ellipse is a curve that is a closed path. It has two constant fixed points.
