Why is moment of inertia of a solid disc smaller than that of a ring?

Moment of inertia depends upon the distribution of mass with respect to the axis of rotation.The greater the distance between the bulk of an object's mass and the axis of rotation, the greater the moment of inertia will be. A solid disk has its mass distributed evenly across its diameter, while a ring has its mass concentrated furthest from the centre of rotation.

What is the equation for inertia?
There are two laws about inertia. The First Law has no formula. It is just a statement that says "an object will continue at constant velocity ,or at rest, until a net force acts on it". This property that requires a force to change its state of motion (or rest) is called the object's "inertia". The Second Law is a formula that describes how an object will move when a net force acts on it. The formula is F = ma. Where, F, is the force and , a , is the objects acceleration. And , m , is the objects mass, which is a measure of the object's inertia. So you could write the formula as a = F/m and in this way you see if the object's mass (inertia) is increased then in order to get the same acceleration you must increase the force. These two laws describe how an object's inertia ,or mass, resists changes in its motion.
How can you find center of mass of solid hemisphere?
Take an elemental mass on the solid hemisphere. Let the mass be in thin form of discs. The centre of mass lies at the centre of the disc. Integrate the whole function to get the c.o.m.
What happens if you cook a compact disc briefly in a microwave oven?
Cooking a compact disc in a microwave is a horrible idea if a person expects to ever use the disc again. It will completely destroy the disc.
WHAT IS NEWTONS DISC?
A Newton disc is a disc with segments in rainbow colours. When the disc is rotated, the colors fade to white; In this way Isaac newton demonstrated that white light is a combination of the seven different colors found in a rainbow. A Newton Disc can be created by painting a disc with the seven different colors. A combination of red, green and blue in the circular disc will yield the same result. This is due to the phenomenon called persistence of vision
A disc is thrown through the air for 1.5 min with a power output of 12.5 W How much work is done when throwing the disc?
A disc is thrown through the air for 1.5 min with a power output of 12.5 W. How much work is done when throwing the disc?
What is the moment of inertia of a disk of radius 12cm and mass 2.4kg from whose edge a circular portion of radius 3cm has been cut off?
It can be done, but it would require taking an integral for the moment of inertia of each particle of the disc... something i don't have the time to do right now ^^;
What is Disc narrowing with spurs?
means that your disc is becoming smaller and smaller (compressed) and that there are fragments of bones on your vertebrates

If a ring sphere and disc of same mass and radius rolls down through an inclined plane which one will reach the foot first?
When rolling down an incline the object with the smallest moment of inertia will get to the bottom first. If your three equal mass objects also have equal radii then the sphere will have the smallest moment of inertia, and will get to the bottom first. Actually, I think neither the mass nor the radii of your objects matters. But I'm not sure. If true, it would mean the sphere always wins regardless of its mass or radius. Spheres always beat disks which always beat rings.
