Newton’s three laws of motion (Wikipedia paraphrased):
First Law: An object at rest tends to stay at rest, or if it is in motion tends to stay in motion with the same speed and in the same direction unless acted upon by a sum of physical forces.
Second Law: A body will accelerate with acceleration proportional to the force and inversely proportional to the mass.
Third Law: Every action has a reaction equal in magnitude and opposite in direction.
It’s interesting how economic development tends to mirror the laws of physics.
First Law: A community or region in motion (growing) will tend to stay in motion until hammered by a major industry restructuring, recession, et. A community or region in downward motion will tend to stay in a downward motion until something gets in its way to retard the decline.
Second Law: Something like – it should be easier to turn around Bathurst than Detroit.
Third Law: There are winners and losers.
