What really is INERTIA?
Is it a force.?
A vector or a scalar?
What can be known only by the defination?
Does it really have anything to do with physics?
Oh, is that what the "a" stands for in that equation? Yeah, I knew that - fixed now.Chi Meson said:Russ:
The high school teacher in me comes out; Inertia is the resistance to change in motion. I know you know that.
Don't know if this is what you're asking, but for me this was once like the question asked in another thread, "What are Field Lines?" If your question is Why is inertia? or, Why does matter resist changes in motion?, then I believe the answer, to date, is, "We don't know." - which is why clive referred to it (correctly) as a phenonemon.gunblaze said:![]()

No. Not even a force in the social sense.Is it a force.?
You raise a question that's been on my mind for some time.cepheid said:Yeah, just to throw in my two cents towards the "phenomenon" camp, I've heard it described this way:
Inertia is a property of matter.
Mass (inertial mass) on the other hand, is a quantity, in fact it quantifies inertia in that it provides a means of physically measuring the effect i.e. we apply a force F to a body, we measure a, we determine what m is, the larger it is, the more difficult a time we had of accelerating the body. What do you guys think of that?
Hey all,in·er·tia [i núrsh?] noun
1.apathy: inability or unwillingness to move or act
2.resistance to change: the property of a body by which it remains at rest or continues moving in a straight line unless acted upon by a directional force
[Early 18th century. From Latin, “lack of skill, inactivity,” formed from iners (see inert

The inability or unwillingness of a person to move or act is only indirectly related to that person's mass.
For some people, inertia can be overcome with money. For others, one has to use brute force, in which case Newton's second law is a reasonable approximation.
A scalar.
No. Not even a force in the social sense.

From a quick look through their forum it seems what you are looking for is the "http://en.wikipedia.org/wiki/Moment_of_inertia" [Broken]"[...]
I'm currently working one a game with realistic physics and I'm use the physics library http://www.bulletphysics.com/" [Broken]. It simulates rigid bodies.
Andrew Mason says Inertia is a scalar but in Bullet it is represented as a vector. [...]
I learned at school (along time ago) that f(force)=m(mass)a(acceleration) but this would be a rule there would be used in Bullet and not a number(vector or scalar).
Any idea on this would be nice. :)
