# An industrial flywheel has a greater rotational inertia when most of its mass is?

On the outer rim. Further away from the axis point.

### A flywheel's diameter is twice that of another of the same shape and mass The larger diameter flywheel's rotational inertia is?

four times the other's Because Rotational Inertia for a flywheel with its axis through the center is I=mr^2; I=m(2r)^2 I =m4r^2

### What is the property of an object that resists changes in rotational motion?

rotational inertia Mass moment if inertia.

### Physical quantity coressponding to inertia is rotational motion?

The physical quantity for rotations corresponding to inertia is the moment of inertia, or rotational inertia. It is represented by the integral of r^2dm.

### Does the rotational inertia of a particular object differ for different axes of rotation?

Yes, rotational inertia depends on the distance of mass from the axis of rotation.

### The product of an object's rotational inertia and its rotational velocity is?

The object's angular momentum

### What are the technologies that operate the law of inertia?

Technologies that operate on the law of inertia make use of the laws of motion for benefit. One of these is the centrifuge which is used to separate matter of different densities from each other. Another is the flywheel which generates energy from storing rotational energy generated when a car brakes.

### How is inertia greater?

inertia becomes greater if the mass of the object is greater. inertia is directly proportional to the mass of the object.

### What is the blank the object the greater is its inertia?

The greater the mass of the object, the greater its inertia.

### The greater the mass of an object the greater it's?

The greater the mass of an object the greater it's inertia The greater the mass of an object the greater it's inertia The greater the mass of an object the greater it's inertia

### Can the mass of an object be considered as constucted at its centrer of mass for purpose of computing its rotational inertia?

No. For the rotational inertia, the distribution of masses is relevant. Mass further from the axis of rotation contributes more to the rotational inertial than mass that is closer to it.

### What is measure of inertia?

Mass is a measure of inertia. Inertia is resistance to a change in motion. Mass and inertia are directly proportional. The greater the mass, the greater the inertia.

### What is physical significance of moment of inertia?

moment of inertia is the rotational equivalent of mass. it is given by I= Mk2 moment of inertia in rotational motion play the same role as mass in linear motion, that is in linear motion f = ma while in rotation, torque= I*Angular acceleration where I is the moment of inertia

### How does inertia affect acceleration?

Inertia can be defined as the relunctance of a body to acceleration. Therefore, the greater the inertia of a body, the less it will accelerate under a given force. Inertia is directly related to mass. The greater the mass, the greater the inertia.

### What is rotational inertia?

Rotational inertia is sometimes called spin. It involves the movement of a mass around an axis. This moving mass will have some measure of kinetic energy that is due to the fact that it is spinning. The variables are the shape and the mass of the object, the way the mass is distributed within the object, the speed of its rotation, and the location of the axis of spin through the object. The moment of… Read More

### What relationship does mass have with inertia?

The mass of an object corresponds to it's inertia. The greater an objects mass the greater it's inertia.

### Are the forces balanced or unbalanced when a car is setting off?

Unbalanced. The rotational force upon the drive wheels must be greater than the force of inertia in order for the car to begin moving.

### Why moment of inertia is called rotational inertia?

That's what it's all about: about rotation. The "inertia" part is because it is comparable to the linear inertia: that's what makes it difficult to change an object's rotation.

### The greater the mass of an object the greater its inertia?

Yes. Mass is what gives an object its inertia.

### How are matter and inertia related?

Matter and inertia are related through mass. Mass is the measure of the amount of matter within an object. The greater the mass, the greater the amount of matter within the object. Inertia is an object's resistance to accelration, and the greater the mass, the greater the inertia.

### What is the relationship between inertia and mass?

The inertia of an object is directly proportional to its mass. The greater the mass the greater the inertia and the lower the mass the lower the inertia. This tells us the fat person will have more inertia due to his greater mass and the thin person will have less inertia due to his lower mass.

### How is mass related to inertia?

the greater the mass, the greater will be the inertia produced in the body when the force is applied on it.

### Why is most of the mass concentrated at the rim in a flywheel?

Most of the mass of a flywheel is concentrated at the rim so as to have a larger moment of inertia for the same mass. This is due to the fact that the moment of inertia varies as the square of the distance from the axis of rotation.

### Why most of the mass is concentrated on rim in a flywheel?

Most of the mass of a flywheel is concentrated at the rim so as to have large moment of inertia for the same mass.This is due to the fact that the moment of inertia varies as the square of the distance from the axis of rotation.

### What does the flywheel do?

A flywheel is a mechanical device with significant moment of inertia used as a storage device for rotational energy. Flywheels resist changes in their rotational speed, which helps steady the rotation of the shaft when a fluctuating torque is exerted on it by its power source such as a piston-based (reciprocating) engine, or when the load placed on it is intermittent (such as a piston pump). Flywheels can be used to produce very high power… Read More

### Does inertia vary with place just like weight?

Nope. While weight is proportional to both mass and the local gravitational field or acceleration, inertia (and by extension momentum) is related only to mass - and special types of inertia, such as rotational inertia, is related only to the distribution of mass (bunched up mass has less rotational inertia than the same amount of mass, only spread out).

### What is an engine flywheel?

A flywheel is on the outside of the motor, typically has fins on it, it is weighted to keep the inertia of the motor spinning to help crank the motor over

### The rotational inertia of an object increase as the mass and the distance of the mass from the center of rotation?

Answer #1: The Rotational Inertia of an object increases as the mass "increases" and the distance of the mass from the center of rotation "decreases". ================================= Answer #2: If Answer #1 were correct, then flywheels would be made as small as possible, and a marble would be harder to spin than a wagon wheel is. An object's rotational inertia (moment of inertia) increases in direct proportion to its mass, and increases in proportion to the… Read More

### The amount of inertia possessed by an object is dependent solely upon its?

Inertia is directly proportional to an objects mass. Inertia is the desire of objects to continue doing exactly what they are doing. The greater the mass the greater the inertia.

### What has greater force of inertia the truck or the man?

Not "force of inertia", just "inertia". The object with the larger mass has the larger inertia.

### What does a baseball rolling along the floor have?

A baseball rolling along the floor has inertia. The amount of inertia depends on the mass of the object. The greater the mass or weight, the greater the inertia.

### Is the tendency for objects to change in their motion called inertia?

Inertia is the tendency for objects to "resist" change. So an object with greater inertia will require a greater force to accelerate it.

### Mass moment of inertia of a flywheel?

define moment of inertia ยง 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).

### How mass affects inertia?

Inertia is the inability of the body to change on its own from its state of rest or of uniform motion along a straight line. This inertia becomes more as mass is more. Hence greater mass = greater inertia.

### What physical characteristic does the moment of inertia of a rotating object most directly and accurately measure?

This is rotational inertia. When inertia forces an object to rotate, it will continue to do so until another force acts upon it.

### What is relationship between mass and inertia?

The more massive a body, the greater the inertia.

### Who has more inertia 1kg ball or 10kg ball?

Inertia is directly proportional to mass. Unless you mean rotational inertia, in which case it depends on the shape, but for two objects of the same shape (and mass distribution), the more massive always has higher inertia.

### What is diff between governor and flywheel?

Both seek to create stability but accomplish that objective using different mechanisms. A flywheel uses its inertia to dampen variation, an obviously passive mechanism. A governor senses and reacts to variation by causing the opposite variation, the objective being a zero sum variability. Other than the active/passive nature, there are considerations as to the nature of variability. The greater the mass of the passive flywheel, the less motive force is required to sustain the desired… Read More

### What is the relation of the force and inertia?

The greater the inertia, the greater is the force required to produce a constant acceleration.(F=ma). But in general, acceleration is not taken constant, in this case, there is no relation between force and inertia.

### What is rotational analog?

The rotational analog is 2nd of newtons law it is the angular acceleration of a rigid object around an axis is proportional to the next external torque on the body around its axis and inversely proportional to the moment of rotational inertia about that axis.

### Why moment of inertia is also called rotational inertia?

Because it is a measure of the "resistence" of an object to be accelerated in its rotation. An object with a big moment of inertia is more difficult to increase/decrease its angular velocity (speed of rotation), than an object with a low moment of inertia.

### Why is mass important when discussing inertia?

The amount of mass affects the amount of inertia. The greater the mass, the more inertia it possesses.

### Can inertia change with mass?

the greater the mass of an object, the more inertia it has, so to answer your ? yes inertia changes depending on mass :]

### Flywheel in the car expensive to repair?

That is a round steel plate bolted to the output end of the crankshaft to which the clutch or the torque converter is attached and into the circumference of which are milled teeth into which the starter pinion gear engages that, by its rotational inertia, smooths the pulsations of the combustion stroke. It makes the engine run smoother. Typically, it is more cost effective to replace the flywheel than it is to repair it. A… Read More
