violated F=ma

[cookbeat01]

Is it totally true, that when Newton's second law (f=ma) is violated, a heavier object when pushed would accelerate at the same rate as a lighter object with the same force? Now don't get me wrong, I do know that physical laws cannot be violated.

well since your breaking a physical law anything can happen. so it can neither be true nor false. or the objects could turn into a spermwhale and a bowl of petunias.

it all depends on how it is violated

No. Let the relationship be [math] \vec F = \frac{m^2}{1 \text { kg}} \vec a[/math], for example. That clearly violates F=ma. Still, two unequal masses would not have the same acceleration when the same force works on them.

lol, nice alien... What is the point of this thread? You're talking about what happens when a physical law is broken.

note though, F=ma isn't fully accurate, just accurate for everyday scales. High forces, speeds or masses, you require relatavistic equations.

It's technically only an approximation on normal scales too. As what do you do if the mass changes?
