Bending Moment – definition, equation, units & diagram

If we apply a sufficient amount of force on a free object, it will move. We already have discussed this concept in an article on Newton’s second law of motion. Now if we want to rotate the free object, we need to apply two parallel forces in the opposite direction. This creates a Torque on … Read more

Rotation of an object by applying a Torque

Newton’s laws of motion tell that translational motion is caused by a force. That means if we apply sufficient force on a body, it will move. But how to rotate an object? Can a force produce the rotational motion of a body? The answer will be yes, but not any type of force. For the … Read more

Kinetic energy of rotation (Rotational kinetic energy)

We already have discussed the kinetic energy of an object and the related facts. A body can have two types of kinetic energies – Translational kinetic energy and Rotational kinetic energy. In this article, we are going to be more specific. Here, we are to explain the rotational kinetic energy i.e. the kinetic energy due … Read more

Formula for moment of Inertia of different shapes

The term Moment of inertia in physics arises for the rotation of an object. Moment of inertia has the same mathematical role in rotational motion as that of the mass in linear motion. But physical significance of the moment of inertia is different from that of the mass of an object. In this article, we … Read more
