The video shows the solution to the following problem:
#Kepler’s first law implies that the equation
of the orbit in plane polar coordinates is
given by the equation of a conic section
If the eccentricity e is in the range ,
then the orbit described by above equation
is a closed ellipse. Use the first two of
Kepler’s laws to deduce Newton’s law of
gravitation.
