Moment of inertia, radius of gyration

The parallel axis theorem is used to estimate the moment of inertia of a rigid body around an axis that is parallel to the object line’s mass (about which the moment of inertia is known). The perpendicular axis theorem notes that the moment of inertia of a rigid body along an axis that is at […]

A simple Harmonic motion is back and forth motion about a fixed axis or a straight line. It can be defined as a type of oscillatory motion or periodic motion.  In SHM, the acceleration acting on the body varies directly with the displacement and is opposite to the direction of displacement. Therefore, the net force

Topple Usually, due to friction, a torque is applied on a body opposing the change of motion and usually due to the quick axis of rotation shifts, if the momentary axis of rotation falls outside the body that time the body topples and this is the condition of toppling. When a torque is applied to

The study of physics relies on the observation of various systems. In order to understand the effect of multiple forces and how they interact with each other, the knowledge of the centre of mass of a system is also imperative. The centre of mass of a system provides an easy correlation to how the body

Introduction Consistent with the perpendicular axis theorem for an axis perpendicular to the plane, the moment of inertia is equal to the sum of the moments of inertia about two mutually perpendicular axes in its plane. Ia = Ib+Ic     (Ia = moment of inertia about the given axis perpendicular to the plane of the

Introduction: The moment of inertia plays an important role in rotational kinematics as in how mass plays an important role in linear kinetics. The common characteristic between them is they resist change. The moment of inertia solely depends on the axis on rotation and varies when this is changed. For a mass, the moment of

The tendency of a force to create rotation is called the moment of a force. The moment of a force is measured over the axis around which a body rotates. Daily activities like opening a door around a fixed hinge or closing a bottle of water involve the moment of a force. The moment of

Introduction to Geostationary satellites A geostationary orbit, also known as a geosynchronous equatorial orbit (GEO), is a circular geosynchronous orbit 35,786 kilometers (22,236 miles) above Earth’s Equator (42,164 kilometers in radius from Earth’s center) that follows Earth’s rotation. Because an object in such an orbit has an orbital period equal to Earth’s rotational period, one

The moment of inertia, in physics, is the measure of the volume of rotating inertia of a body, i.e., the resistance of the body showing its rotational speed relative to the axis altered by torque. The axis can be internal or external and can be tilted or straight. The moment of inertia (I) is always

Introduction A rigid body system’s centre of mass is an important feature. Usually, more than one particle is present in these systems. It’s crucial to look at these systems as a whole. These bodies must be treated as a single point mass to perform mechanical calculations. A position like this is referred to as the
