## What is inertia G in Catia?

Moment of inertia of the object about the ox axis with respect to the system Gxyz, where G is the center of gravity. … Moment of inertia of the object about the ox axis with respect to the system Axyz, where A is a selected axis system.

## How do you measure the moment of inertia of an object?

The moment of inertia of any object can be experimentally measured by suspending the object through its center of mass with a single cable. The moment of inertia can be calculated by twisting the object about the axis of the cable and measuring the period of the oscillation [7].

## How do we measure inertia?

There are two numerical measures of the inertia of a body: its mass, which governs its resistance to the action of a force, and its moment of inertia about a specified axis, which measures its resistance to the action of a torque about the same axis. See Newton’s laws of motion.

## Does speed affect inertia?

For both interpretations, the answer is ‘yes‘ since force still acts in an opposite force on anything which has mass. As you accelerate, your velocity increases and therefore mass will increase. The increase in mass will bring about an opposite force. The greater the mass, the greater the inertia.

## What object has more inertia?

Inertia is a force which brings all objects to a rest position. All objects have inertia. A more massive object has more inertia than a less massive object. Fast-moving objects have more inertia than slow-moving objects.
