The parallel axis theorem states that the "moment of inertia of any object about an axis through its center of mass is the minimum moment of inertia for an axis in that direction in space," according to HyperPhysics. It ... More »

Calculating the moment of inertia for a rod requires you to know the mass, length and location of the rotational axis. An estimation may be required with regards to the position of this axis. More »

The law of inertia states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The law of inertia is sometim... More »

The moment of inertia of a solid cylinder is equal to one half of the mass multiplied by the square of the radius. This equation should be used to find the cylinder's moment of inertia with respect to the z-axis, or the ... More »

Northwestern University explains that a ring has a higher moment of inertia than a solid disk of equal mass and outer radius because it has less mass at its center. According to the principles of inertia, bodies that hav... More »

The formula used to determine inertia is "I= mr²," where "I" is the rotational inertia unit, "m" is the mass of a single point of movement and "r" is the distance of that point from the axis of rotation. The accepted way... More »
