how does the magnitude of the velocity affect a planet’s orbit? Use the words circular and elliptical in your answer. 10. In this step you will investigate how the direction of the velocity affects the orbit. You will be keeping the magnitude of the velocity at the original preset of 120. Additionally, you will keep the . mass of body 2 = 0.1

Elliptical Orbits. Radius vector of planet sweeps out equal periods in equal times. P2 = a3. Geometrical Properties of Elliptical Orbits. r + r’ = 2a = constant (1-1) by defn of ellipse. b2 = a2 - a2e2 = a2(1-e2) (1-2) from Pythagorean theorem. where a = semimajor axis of ellipse. b = semiminor axis. e = eccentricity

How to calculate orbital velocity in an elliptical orbit - Quora
Now we know how to find the velocity of an object in a circular orbit and an elliptical orbit. What else do we need to know to successfully make a Hohmann Transfer? Label the diagram below to help find the velocity at the perigee and apogee: We know that the velocity of an object in an elliptical orbit is.

This is an elliptical orbit! If the energy is positive, the object will fly out into space (it has achieved escape velocity) and will never come back (see the picture below). An object with negative energy, but more energy than that needed for a stable orbit, will undergo approximately simple harmonic motion in this potential well.

1. A circular orbit and a highly elliptical orbit are shown in the diagram below. Draw and label the net force (F) and velocity (v) vectors for each of the six marked positions for a counter-clockwise orbit. Draw the vectors in the appropriate direction and of the proper magnitude (relatively speaking). 2.
