Point of inertia formula

WebFeb 20, 2024 · To expand our concept of rotational inertia, we define the moment of inertia I of an object to be the sum of m r 2 for all the point masses of which it is composed. That is, I = ∑ m r 2. Here I is analogous to m in translational motion. Because of the distance r, the moment of inertia for any object depends on the chosen axis. WebThe term inertia may also refer to the resistance of any physical object to a change in its velocity. This includes changes to the object's speed or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed when no forces act upon them.
