noun
- 1. a tendency to do nothing or to remain unchanged: "the problem runs deeper than bureaucratic inertia"
- 2. a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force: "the power required to overcome friction and the inertia of the moving parts"

In this piece of article, let us discuss the first law of inertia in detail. Before discussing the law of inertia, let us know the Inertia Definition. Inertia is defined as a property of matter by which it remains at the state of rest or in uniform motion in the same straight line unless acted upon by some external force. Table of Contents:
In general form, moment of inertia is expressed as I = m × r2. where, m = Sum of the product of the mass. r = Distance from the axis of the rotation. And, integral form: I = ∫dI = ∫0M r2 dm. ⇒ The dimensional formula of the moment of inertia is given by, M 1 L 2 T 0.
The inertia of Motion: When the resistance is offered by the body to continue to be in uniform motion unless an external force acts on it. e.g., the passengers fall forward when a moving bus stops suddenly due to inertia of motion. Suggest Corrections. 145.

1. Inertia of rest: An object will remain in place until you or something else moves it. (Dust particles, for example, remain at rest until a carpet is shaken.) 2. Inertia of motion: When a force does not act on an object, it continues to move at the same speed. (When a car comes to a stop, for example, the body moves forward.)
Assignment: If the moment of inertia of a body along a perpendicular axis passing through its centre of gravity is 50 kg·m 2 and the mass of the body is 30 Kg. What is the moment of inertia of the same body along another axis, which is 50 cm away from the current axis and parallel to it? Solution: From the parallel axis theorem,
Inertia. Momentum is a vector quantity as it is the tendency of a body to remain in motion. Inertia is a scalar quantity as it is the resistance offered by the body to any change in its velocity. Momentum is denoted as ‘ p ’. Inertia is denoted as ‘ I ’. The momentum of a body of mass ‘m’ moving with a velocity of ‘ v ’ is ...
The moment of inertia is a fundamental property of a physical object that describes its resistance to changes in rotational motion. It plays a crucial role in various areas of physics and engineering. A moment of inertia is a measurement of a body's resistance to angular acceleration about a certain axis. Check here moment of inertia formulas ...
It is given as follows: I G = ∫ r 2 dm. Mass moment of inertia is also used in different rigid body rotation problems. These include the following: ( ΣM G = I G α ) F = ma analysis moment equation. ( T = ½ I G ω 2 ) Rotational kinetic energy. ( H G = I G ω ) Angular momentum. The mass moment of inertia unit is kg.m 2 and lb.in 2.
Explain the following: (I) Inertia of rest (ii) Inertia of motion (iii) Inertia of direction. Inertia is the natural tendency of an object to resist a change in its state of motion or of rest. Note: The mass of an object is a measure of its inertia Inertia of direction: Inertia of direction is the fundamental property possessed by a body to ...
