Why is force defined as mass x acceleration instead of mass x velocity?
> If an object is moving at a fixed rate of speed (velocity = x), the acceleration would be 0, yet it would still have force. But an object moving at a fixed speed doesn't have any forces acting upon it (or more correctly, all forces acting on it cancel out). Why do you want to redefine physic…
The Short Answer
> If an object is moving at a fixed rate of speed (velocity = x), the acceleration would be 0, yet it would still have force. But an object moving at a fixed speed doesn't have any forces acting upon it (or more correctly, all forces acting on it cancel out). Why do you want to redefine physical units?
