For a point mass, the moment of inertia is just the mass times the square of perpendicular distance to the rotation axis, i = mr2.
How to Calculate Inertia?
Inertia is a measure of an object’s resistance to changes in its state of motion. It is the tendency of an object to remain at rest or in uniform motion in a straight line unless acted upon by an external force. Inertia is an important concept in physics, and is the basis of the law of inertia, which states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
Calculating the inertia of an object can be done using the equation for moment of inertia, which is expressed as I = mr2, where m is the mass of the object and r is the radius of the object. Moment of inertia is a measure of an object’s resistance to changes in its angular velocity.
The moment of inertia can be calculated in two ways. The first method is to use the equation I = mr2 and substitute in the mass and radius of the object. The second method is to use the parallel axis theorem, which states that the moment of inertia of an object is equal to the sum of the moments of inertia of the individual components of the object.
For example, if we are looking to calculate the inertia of a disk, we can first calculate
