If we apply a sufficient amount of force on a free object, it will move. We already discussed this concept while explaining Newton’s second law of motion. Now if we want to rotate the free object, two parallel forces should be applied in the opposite direction on two sides of the object. This creates a … Read more
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
We 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 to the … Read more
The term Moment of inertia is used in physics to describe the rotation of an object. The moment of inertia has the same mathematical role in rotational motion as that of the mass in linear motion. But the physical significance of the moment of inertia is different from that of the mass of an object. … Read more
