This was an extra credit project for my Exploration of Space course Spring 2009. One of my more creative endeavors:-D

Keplers Laws All Three

A natral orbits controlled by gravity

Celestial Bodies all follow, follow one.

Spaceships with their engines off, orbit in one too

Keplers Laws explain them and theres only 3 to know

Orbits arent circles

The planets move in ellipses you see

Suddenly I see (Suddenly I see)

Pariapsis is close to gravity

Suddenly I see (Suddenly I see)

Apopapsis is farthest from gravity

Suddenly I see (Suddenly I see)

For earth close is perigee

Suddenly I see (Suddenly I see)

The farthest from the Earth is apogee

The first law talks about the orbits shape

If its bound its elliptical, elliptical.

Theres 2 foci with the occupied

The major axis is the largest diameter of it

Unbound orbits

Are called hyperbolic in shape

Suddenly I see (Suddenly I see)

Round means low eccentricity

Suddenly I see (Suddenly I see)

Our planets make orbits like these

Suddenly I see (Suddenly I see)

Stretched is high eccentricity

Suddenly I see (Suddenly I see)

Astroids and comets are like these

[

And the second law is

At the pariapsis and slowest at apoapsis

The third law talks about the period

The time to make an orbit

The bigger the major axis the longer the period

The bigger the major axis the greater total energy

Periapsis has the greatest energy of motion

Apoapsis has the greatest energy of position

Total Energys the same at any point in orbit

Suddenly I see (Suddenly I see)

Total Energys the sum

Suddenly I see (Suddenly I see)

Of energy of motion and position

Suddenly I see (Suddenly I see)

The sum is constant

Suddenly I see (Suddenly I see)

Because of conservation of energy

Suddenly I see (Suddenly I see)

Bound orbits have negative total energy

Suddenly I see (Suddenly I see)

Unbound have positive total energy

Suddenly I see (Suddenly I see)

These are Keplers Laws all three

Suddenly I see (Suddenly I see)

They explain the solar system cant you see.
