    Formula Inertia
AI Thread Summary
Inertia is fundamentally linked to mass, representing an object's resistance to changes in its state of motion. While some participants argue that inertia is not quantifiable, others clarify that it can be expressed through a particle's mass or an inertia matrix for extended bodies. The discussion references Newton's laws, particularly emphasizing that inertia relates to the force required to change an object's velocity. The consensus is that while inertia is a property of mass, it can be quantified in specific contexts. Understanding inertia is crucial for physics projects and applications.

Hey everyone! I love this site!

Im doing a project on Inertia and I need to know the Formula. Does anyone know what it is?
 
Physics news on Phys.org
You'll have to be a bit more specific than that!
 
The index of your textbook ... "Newton's first law"
 
F = Ma?
 
Is there really a formula for intertia? Isn't it just mass? The tendency for a mass to remain at constant velocity/rest. Mass and/or inertia is like a measure of resistance in a change of velocity. So the higher the mass the more force you need to accelerate it at a certain rate.
 
Yes.. Inertia is just the property which defines the resistance the moving or a stable object offers towards the external applied force. as the mass of the object increases its inertia increase.. its not quantifiable...

I have to disagree there; the inertia for a specific body is definitely quantifiable. A particle's inertia is simply it's mass, whereas one can express the inertia of an extended body as an inertia matrix. Either way, one can definitely quantify the inertia of a specified mass distribution.
