The moment of inertia is a tensor relating the angular velocity to the energy in angular motion and the angular momentum of a rigid body, and the angular acceleration to the torque.

Roughly speaking, it is to angular motion what mass is to linear motion. The formula can be found at http://en.wikipedia.org/wiki/Moment_of_inertia .

# What is moment of inertia?

A2 Moment of inertia is the term used to measure or quantify the amount of mass located at an object's extremities. For example if all the mass of an object was located in a

# What is the moment of inertia of a molecule?

The moment of inertia of a molecule is the mass property that isheld by a molecule. This determines the necessary torque of adesired angular acceleration concerning the axis o

# Who introduced the concept of moment of inertia?

it was intoduced by Galileo

# What is physical significance of moment of inertia?

moment of inertia is the rotational equivalent of mass. it is given by I= Mk 2 moment of inertia in rotational motion play the same role as mass in linear motion, that is i

# Define moment of inertia?

inertia is that property of a mass which resist change in its state of rest or motion.

# Is moment of inertia scalar or vector?

i think it is neither a vector nor a scalar but a TENSOR.

# Mass moment of inertia of a flywheel?

define moment of inertia Ă‚Â§ I is the moment of inertia of the mass about the center of rotation. The moment of inertia is the measure of resistance to torque applied on

yes

# What is difference between polar moment of inertia and moment of inertia?

Polar moment of inertia of an area is a quantity used to predict an object's ability to resist torsion.Moment of inertia, also called mass moment of inertia or the angular mas

# What is the formula for moment of inertia?

You have to multiply each small unit of mass with the square of the distance from the axis of rotation. This requires an integration, but you can find tables which have this i

# What variables contribute to moment of inertia?

The axis about which the body is being rotated and the geometry of the body are important. The further away material (in terms of area) is from the centroid of the body the

# What is the moment of inertia of a cylinder?

# Why moment of inertia is called rotational inertia?

That's what it's all about: about rotation. The "inertia" part is because it is comparable to the linear inertia: that's what makes it difficult to change an object's rotation
