RE: [SPAM] RE: DPC limitations?

Adding mine before Peter locks the thread:)

If we are talking about revolution and the scope are limited to Newtonian, I
think it’s due to:

  1. the distance between 2 objects.
  2. the mass of 2 objects (gravitational force).
  3. the velocity of the moving object.

The projectile of the object can be solved by establishing a second order
ordinary differential equation derived from Newton’s Second Law, with
initial values (initial position and velocity) properly prescribed.

Assuming energy is conservative during the entire motion, i.e. the object is
neither losing energy nor accelerated by gradational force of other
objects), the projectile solely depends on the initial values.
The following results are possible:
a) the object eventually falls down (parabolic, or straight line).
b) the object revolves around the sun. (elliptic or circular)
c) the object escapes from the field (hyperbolic)

Only #b will keep us around the Sun.

All this time I thought it was momentum … :wink:

Differences of opinion are what make the world go around though :slight_smile:
