Which statement is correct for moment of inertia? Statement-1: The moment of inertia of a rigid body reduces to its minimum value as compared to any other parallel axis when the axis of rotation passes through its centre of mass. Statement-2: The weight of a rigid body always acts through its centre of mass in uniform gravitational field.
What is inertia answer?
Inertia is the resistance of any physical object to any 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.

What is the moment of inertia of a circular section about an axis perpendicular to the section?
Moment of inertia of a circular section about an axis perpendicular to the section is. πd3/16.
What does the moment of inertia describe?
moment of inertia, in physics, quantitative measure of the rotational inertia of a body—i.e., the opposition that the body exhibits to having its speed of rotation about an axis altered by the application of a torque (turning force).
What is moment of inertia in simple terms?
: a measure of the resistance of a body to angular acceleration about a given axis that is equal to the sum of the products of each element of mass in the body and the square of the element’s distance from the axis.
Which of the following is true about inertia inertia is?
Inertia is simply the tendency of an objects to resist a change in whatever state of motion that it currently has. … True – Mass is a measure of an object’s inertia. Objects with greater mass have a greater inertia; objects with less mass have less inertia.
What is inertia easy?
From Simple English Wikipedia, the free encyclopedia. Inertia is the resistance of the object to any change in its motion, including a change in direction. An object will stay still or keep moving at the same speed and in a straight line, unless it is acted upon by an external unbalanced force.
What is inertia 11th?
The tendency of all the objects/bodies to resist the change in their motion is called inertia. That is, an object/body at rest will stay at rest until and unless a force causes it to move. Similarly, an object/body in motion will stay in motion until and unless a force causes it to stop or change its speed.
What is inertia for class 9th?
Inertia. Defintion: Inertia is a property or tendency of every object to resist any change in its state of rest or of uniform Force and Laws of Motion. It is measured by the mass of an object. The heavier the object, the greater will be its inertia.
What is the moment of inertia of a circular ring?
The moment of inertia of a circular ring about an axis perpendicular to its plane passing through its centre is equal to $M{{R}^{2}}$, where M is the mass of the ring and R is the radius of the ring. Hence, $I=M{{R}^{2}}$.
What is the moment of inertia of a circular ring of mass M and radius R about its diameter?
MR2/2.
What is the moment of inertia of a spherical shell?
A spherical shell is a hollow sphere and the moment of inertia of the hollow sphere about an axis through the center is [dfrac{2}{3}M{{R}^{2}}]. But for a solid sphere, it is [dfrac{2}{5}M{{R}^{2}}]. So we must be very careful while taking moments of inertia for the sphere.
What is moment of inertia of ring?
The moment of inertia of a circular ring about an axis perpendicular to its plane passing through its centre is equal to $M{{R}^{2}}$, where M is the mass of the ring and R is the radius of the ring. Hence, $I=M{{R}^{2}}$.
What is the moment of inertia of a square plate?
