How to set up an overall equation in physics?
Hello everyone,
At school, we did an experiment on circular motion. We looked at the centripetal force and how it depends on mass, radius, and angular velocity. This resulted in three equations that are linear regressions.
F= 6.34N/kg * m + 0.002 ; F= 2.6N/kg *r – 0.026; F= 0.187N/kg * w – 0.421
As in my question, I would need an overall equation where all three regressions are together.
my idea:
Just write everything together except the Y coordinate, which you just add together.

Before you can work with these equations, they have to vote first. Up to N/kg * m, the units do not vote or are missing. If F is to be a force, the equation must also give a force.
N/kg * m is ok, because N comes out, that is a force unit.
But this does not work with N/kg * r and N/kg * ω. Instead of N/kg, there must be a unit which, multiplied by r or ω, produces a force unit.
The numbers 0.002, – 0.026 and – 0.421 cannot thus be in a force equation. Without units, they do not represent physical variables.
I see again and again that people write where ω is meant. This is causing confusion and confusion. Guys, please let you know how to write Greek letters on the computer. Let’s go!
