YES. Infact, an object can have infinitely different moment of inertias. It all depends on the axis about which it it rotating.
You can allow an object to rotate about any axis (this may or may not pass through the object).

Does a speeding car or a jet on a runway have more inertia?
A speeding car and a jet on a runway would have roughly the same amount of inertia, as both objects have mass and are in motion. Inertia is a property of an object that resists changes in its motion, and is directly proportional to the object's mass. Therefore, the greater the mass, the greater the inertia.
When the mass of one object is considerably Less than the mass of another object is the action-reaction force not noticeable?
If the MASS of the 1st Object in a COLLISION is too small to generate a FORCE large enough to overcome the INERTIA of the 2nd Object, then the more massive Object will not move. This could make it look like the more massive object is not REACTING to the Collision.
What would happen to an object in orbit around planets if the planets force of gravity were stronger than the objects inertia?
The object would crash into the planet.
What would happen to an object in orbit around a planet if the planets force of gravity were stronger than the objects inertia?
The object would crash into the planet.
When applying a force to make an object move why is it most effective to have the applied force aimed directly at the objects center of mass?
The question is based on the false assumption that imparting a rotational motion on an object is not making it move.Applying the force which is not aimed directly at the centre of mass imparts a rotational as well as a translational motion. Why should this be considered any less than only rotational or only translational motion?
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.
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.
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 thedistance 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 proportionto its mass, and increases in proportion to the square of the distance of themass from the center of rotation.
Why does a heavy thing go further than a lighter thing?
because of inertia if the mass of the object is more than inertia also be more
Does a cart loaded with groceries have more inertia because it has more mass than an empty cart?
True. Mass is the only way to measure inertia. more mass = more inertiaYes, a cart loaded with groceries has more inertia because it has more mass than the empty cart. The inertia of any object is determined by the amount of its mass.Truetrue
Which of the following has more inertia than a 100 g object on Earth?
Any object that has a mass greater than 100 gram, will also have more inertia. By the way whether it is on Earth or not is irrelevant. If you take a 100-gram mass anywhere else, it will still have 100 gram; and the inertia (which depends on the mass) will also be the same.
Does a heavier object have more inertia than a lighter object?
Yes because according to newton 1st law
What exactly is inertia?
Inertia is the resistance of motion of an object. The more inertia, the harder it is to move something. The less inertia, the easier it is to move. Take a bowling ball and a marble. The marble can be flicked by the finger, because it has less inertia. The bowling ball takes the entire hand because it has more inertia than the marble. According to Newton's laws, an object that is moving tends to continue in motion. A moving object has inertia as it has Mass and Velocity. An object that is not moving requires a Force exerted on the Mass to start it moving.
List 2 unique and different examples of an object having inertia?
You, and I are two unique objects and we both have inertia. Anything with mass has inertia. I probably have more inertia than you, because my mass is about 113.63 kg, and you are likely to have less mass than that.
Do heavier objects roll down a hill faster than lighter ones?
Rolling is more complicated than falling, because rotational inertia is involved. Without that factor, in an ideal world this is the same as asking if a heavier object falls faster than a lighter one. The answer to that question (again, in an ideal world) is no. In the real world... it might, or it might not, it depends on the exact circumstances. There's no fundamental reason that it should if the objects have similar construction (i.e. moments of rotational inertia), but friction and wind resistance complicate things.
Why does a semi truck have more inertia?
Inertia is a measure of how resistant an object's motion is to changing that motion, and is related to the mass of an object. Increase mass and inertia increases; decrease mass and inertia decreases. For an object to have greater inertia, it must therefore have greater mass. Semi- trucks are very massive vehicles, much more than others normally found, so they will have more inertia than anything else driven on roads. An average car or light truck might have a mass of 1 to 2 tonnes; semis usually have many tens of tonnes mass.
Does a heavier object always have more inertia than a lighter object?
Inertia is "rotary momentum"; an object's ability to continue spinning when a decelerating force is applied.Just as a heavy object takes more effort to stop from the same speed as a light object, so does a heavy object take more effort to stop from turning at the same speed as a light object.So assuming they are turning at the same angular velocity, the heavier one has a larger inertia. Otherwise, remember that inertia is also proportional to angular velocity.
