Moment of inertia at a point away from centre of mass is a measure of an object's resistance to rotational motion when it is rotated about that point. It takes into account the mass distribution of the object and the distance of the point from the centre of mass.
The moment of inertia at a point away from centre of mass can be calculated using the formula I = mr², where I is the moment of inertia, m is the mass of the object, and r is the distance between the point and the centre of mass.
The moment of inertia at a point away from centre of mass directly affects an object's rotational motion. The higher the moment of inertia, the more resistance an object will have to rotational motion. This means that it will require more torque or force to rotate the object.
The moment of inertia at a point away from the centre of mass is generally higher than the moment of inertia at the centre of mass. This is because the further away the point is from the centre of mass, the more distributed the mass of the object is, resulting in a higher moment of inertia.
The moment of inertia at a point away from centre of mass can be affected by the shape, size, and mass distribution of the object. The further the point is from the centre of mass, the higher the moment of inertia will be. Additionally, the moment of inertia can also be affected by the object's rotation axis and the distribution of mass around that axis.
