Graphs and Ellipses

Imagine the challenge of getting the space shuttle to rendezvous with the International Space Station. Groups must determine the elliptical transfer orbit needed to get the space shuttle from its orbit to the orbit of the International...

Orbital velocity of planets change. Kepler's Second Law of Motion attempts to explain and predict the change in velocity. Scholars learn how to apply this law as they watch the video lesson.

The class examines graphs in the form r = F(¿¿) in polar coordinates (r, ¿¿), in particular with the circle, ellipse and other conic sections. They determine the nature of an ellipse by studying the role of the semimajor axis and...

Using an online planetary simulator, astrophysics high schoolers explore each of Kepler's laws. The 13-page printable handout walks them through the activity, which also includes using string, pushpins, and a pencil to model three...

High schoolers become acquainted with linear graphs, the parabola and the rectangular hyperbola. Also prepare tables of paired values as preparation for plotting a line. They study the cartesian equation of an ellipse, with a worked...

Learners explain that planets actually orbit the center of gravity of the solar system, and that distant planets may be detected by motions of their central star around the centers of gravity of their planetary systems.
