# What is the unit of moment of inertia for a rotating molecule?

## What is the unit of moment of inertia for a rotating molecule?

kilogram-metre square
The unit of moment of inertia is a composite unit of measure. In the International System (SI), m is expressed in kilograms and r in metres, with I (moment of inertia) having the dimension kilogram-metre square.

### What is the moment of inertia of a rotating rigid body?

I=MR2. Moment of inertia of rigid body depends upon the distance of the mass from the axis of the rotation. It is independent from the angular velocity of the rotation.

What is moment of inertia and its unit?

Moment of inertia is defined as the tendency of an object to remain in a state of rest or of a constant rotational velocity. Greater the moment of inertia, more torque is required to change this state. Torque in rotational motion plays the same role as force in linear motion. Its SI unit is kg. metre2.

What is the unit of product of inertia *?

What is the unit of product of inertia? Explanation: The unit of product of inertia is same as that of moment of inertia I.e. mm4. 10.

## What unit is Mi?

Unit of Moment of Inertia is One kilogram per square meter (kg-m2).

### What is the unit of mass moment of inertia Mcq?

What is the unit of mass moment of inertia? Explanation: The mass moment of inertia is the product of moment of inertia and area. So L4 x L2 = L6. so its unit will be m6.

What is rotation of rigid body?

Rigid body rotation is a motion that occurs when a solid body moves in a circular path around something. The rotational motion can be broken down into two types of rotation – Rotation about a fixed axis and rotation about a fixed point.

What is the rotational analog to F MA?

T = Ix
For objects that rotate, the equation for rotational motion, T = Ix is analogous to F = ma. Torque (T) corresponds to Force (F). Angular Acceleration, x, corresponds with “translational” Acceleration, a.

## What is the unit of moment of inertia selected a mm2 B mm3 C mm4 D mm5?

Explanation: The unit of product of inertia is same as that of moment of inertia I.e. mm4.

### What units are used to measure mass?

Mass is used to measure the weight of an object. For example, you are measuring the mass of your body when you step on to a scale. In the metric system of measurement, the most common units of mass are the gram and kilogram.
