Moment of inertia is a measure of an object's resistance to changes in its rotational motion, based on its mass distribution. Moment of force, also known as torque, is a measure of the rotational force applied to an object to produce rotational motion. In essence, moment of inertia describes an object's inherent property, while moment of force describes an external force acting on an object.

What is the difference between torque and moment of inertia?
Torque is the measure of the rotational force applied to an object, causing it to rotate around a pivot point. Moment of inertia, on the other hand, is a measure of an object's resistance to changes in its rotational motion. Torque depends on force and the distance from the pivot point, while moment of inertia depends on an object's mass distribution and shape.
What is difference between polar moment of inertia and moment of inertia?
Polar moment of inertia of an area is a quantity used to predict an object's ability to resist torsion.Moment of inertia, also called mass moment of inertia or the angular mass, (SI units kg m2, Imperial Unit slug ft2) is a measure of an object's resistance to changes in its rotation rate.
What are the types of moment of force?
Don't know what the textbooks might tell you but I think this list of moments of inertia is rather comprehensive: rectangle circle cylinder hollow cylinder i beam triangle rod square disk area mass sphere hoop rotational t section ring shaft semi circle But these are moments of inertia. Not clear what you mean by moment of "force." Of course there is a force associated with moments of inertia. And that's the force F that is turning the object that has the inertia. In general that force is F = Ia where I is the moment of inertia and a is angular acceleration of the object.
What is different between inertia and moment of inertia?
The ability of a body to maintain its state, either in motion or in rest position against any external force is called Inertia while the moment of inertia is defined as the measure of an object's resistance to any change in its state of rotation.
What is the moment of inertia of a hoop and how does it affect the rotational motion of the hoop?
The moment of inertia of a hoop is a measure of its resistance to changes in its rotational motion. It depends on the mass distribution of the hoop. A hoop with a larger moment of inertia will require more force to change its rotation speed compared to a hoop with a smaller moment of inertia. This means that a hoop with a larger moment of inertia will rotate more slowly for a given applied torque, while a hoop with a smaller moment of inertia will rotate more quickly.

What is meant by moment of inertia in Induction motors?
The second moment of a force is called as moment of inertia.

Mass moment of inertia of a flywheel?
define moment of inertia§ I is the moment of inertia of the mass about the center of rotation. The moment of inertia is the measure of resistance to torque applied on a spinning object (i.e. the higher the moment of inertia, the slower it will spin after being applied a given force).

Is there a difference between gravity and inertia?
Yes, gravity is the force of attraction that exists between all objects with mass, pulling them toward each other. Inertia, on the other hand, is the resistance of an object to changes in its state of motion. Gravity is a force that acts on objects, while inertia is a property of objects themselves.
What is the difference between centripetal force and inertia?
Centripetal force is the force directed towards the center of a circular path that keeps an object moving in a circle, while inertia is the tendency of an object to resist changes in its state of motion. Inertia is a property of an object, while centripetal force is the external force required to keep an object moving in a curved path.

What friction is used while opening a door?
While opening the door you do work to generate a moment of inertia that opens the door. The moment of inertia= force applied x perpendicular distance between the point of application of force and the axis of rotation. The greater the perpendicular distance the easier it is for you to open the door, i.e. a less amount of force can be applied to open the door. I hope this was useful.
What is the purpose calculating moment of inertia?
Inertia is affected by an outside force. So if you calculate the moment of inertia, you calculate the magnitude and possibly the direction of the outside force. You can use this to determine acceleration.
