F=ma derived from scratch
F=m*a is probably the most famous equation in physics. If a force F acts on a mass m to produce an acceleration a then F=m*a.
Or another way to look at this. If you find a mass m undergoing an acceleration then look around. You'll find a force F and F=m*a.
But there's yet another way to look at this. If flux is the number of force lines through space then the rate of change of flux is a force. This is certainly true in electromagnetism where it's called Faraday's Law.
Faraday's Law - When the magnetic flux linking a circuit changes, a force is induced in the circuit proportional to the rate of change of the flux linkage.
Let's assume this is also true for gravity..
Gravitational equivalent - When the gravitational flux linking a circuit changes, a force is induced in the circuit proportional to the rate of change of the flux linkage.
The number of lines of force is determined my m. And the rate of change is determined by a. So F=m*a
