Where is the greatest rotational inertia?
Rotational inertia is directly proportional to the mass of the object. Eliminate (A) and (B), as they have smaller masses. The farther away the mass is from the axis of rotation, the greater the rotational inertia.
What causes greater rotational inertia?
In summary, the larger the distance the four adjustable masses are from the axle, the larger the rotational inertia, and therefore the larger the resistance of the demonstrator to angular acceleration.
Does rotational inertia increase with mass?
Indeed, the rotational inertia of an object depends on its mass. It also depends on the distribution of that mass relative to the axis of rotation. When a mass moves further from the axis of rotation it becomes increasingly more difficult to change the rotational velocity of the system.
Which object had the greater rotational inertia?
Which has greater inertia? Explanation: The inertia of an object is its resistance to change its position if not in motion or its resistance to changing its motion for a moving object. Inertia is a definition of mass so an object with greater mass will have greater inertia.
What does higher rotational inertia mean?
Higher moments of inertia indicate that more force has to be applied in order to cause a rotation whereas lower moments of inertia means that only low forces are necessary. Masses that are further away form the axis of rotation have the greatest moment of inertia.
Which has larger moment of inertia?
Moment of inertia is larger when an object's mass is farther from the axis of rotation. , where d is the distance from the initial axis to the parallel axis. Moment of inertia for a compound object is simply the sum of the moments of inertia for each individual object that makes up the compound object.
How do you increase rotational inertia?

What does rotational inertia depend on?
Rotational inertia depends both on an object's mass and how the mass is distributed relative to the axis of rotation. Unlike other scenarios in physics where we simplify situations by pretending we have a point mass, the shape of an object determines its rotational inertia.
Which has the greater moment of inertia?
Higher moments of inertia indicate that more force has to be applied in order to cause a rotation whereas lower moments of inertia means that only low forces are necessary. Masses that are further away form the axis of rotation have the greatest moment of inertia.
Which moment of inertia is greater all have the same mass and a radius?
If two objects have the same mass and radius, but different distributions of the mass, their moments of inertia will be different. For example, the moment of inertia of object B will be higher compared to A, if both objects are of the same mass, since the mass is located at larger radii in case of B.
Which of the following has the highest moment of inertia when each of them have the same mass and the same radius?
1 Answer. Thus, Ihollowsphere I h o l l o w s p h e r e is largest.
Which has a greater moment of inertia?
Higher moments of inertia indicate that more force has to be applied in order to cause a rotation whereas lower moments of inertia means that only low forces are necessary. Masses that are further away form the axis of rotation have the greatest moment of inertia.
What is the rotational inertia of an object?
Rotational inertia or moment of inertia, quantifies the resistance of an object to any change in its initial state of rotation. It depends on the object's mass and the distribution of the mass from the axis of rotation. It has an SI unit of kg⋅ ⋅ m2 2 .
How do you find the rotational inertia?
Rotational inertia is a scalar, not a vector and is dependent upon the radius of rotation according to the formula rotational inertia = mass x radius^2. Rotational inertia, rotational inertia is the measure of an object's resistance to change in its rotation.
Which of the following has the largest moment of inertia?
So among all options four rods forming square of side 2a has highest moment of inertia of 4ma2/3 about an axis passing through its center of mass and perpendicular to the plane of body.
Which of the following has the highest inertia?
Best Answer Hence, the human body has the highest mass; thus, it has the highest inertia. Inertia is a property of an object to resist changes in its current state of motion, and it is directly proportional to the mass of the object.
Which of the spheres has the largest moment of inertia?
A hollow sphere will have a much larger moment of inertia than a uniform sphere of the same size and the same mass.
Does rotational inertia depend on radius?
Rotational inertia is a scalar, not a vector and is dependent upon the radius of rotation according to the formula rotational inertia = mass x radius^2. Rotational inertia, rotational inertia is the measure of an object's resistance to change in its rotation.
Which of the following has highest moment of inertia when each of them of same mass and same diameter?
1 Answer. Thus, Ihollowsphere I h o l l o w s p h e r e is largest.
Which of the following has largest moment of inertia a ring about its axis perpendicular to its plane B disc about its axis perpendicular to its plane C solid sphere?
So among all options four rods forming square of side 2a has highest moment of inertia of 4ma2/3 about an axis passing through its center of mass and perpendicular to the plane of body.
Which of the following has the greatest moment of inertia for the ring and disc of the same mass and same radius?
A ring has greater moment of inertia than a circular disc of same mass and radius, about an axis passing through its centre of mass perpendicular to its plane, because. Answer: A ring has a larger moment of inertia because its entire mass is concentrated at the rim at a maximum distance from the axis.
Which of the following has largest moment of inertia of ring about its axis perpendicular to its plane?
So among all options four rods forming square of side 2a has highest moment of inertia of 4ma2/3 about an axis passing through its center of mass and perpendicular to the plane of body.
Which of the following has the highest moment of inertia when each of them had the same mass and the same radius?
1 Answer. Thus, Ihollowsphere I h o l l o w s p h e r e is largest.
Why is the moment of inertia of a ring greater than a disk?
A ring has greater moment of inertia than a circular disc of same mass and radius, about an axis passing through its centre of mass perpendicular to its plane, because. Answer: A ring has a larger moment of inertia because its entire mass is concentrated at the rim at a maximum distance from the axis.
Which of the following has the highest moment of inertia when each of them of same mass and diameter?
1 Answer. Thus, Ihollowsphere I h o l l o w s p h e r e is largest.
Which of the following has the highest amount of inertia?
Hence amongst the following options, the human body has the highest mass thus it has the highest inertia. Inertia is a property of an object to resist changes in its current state of motion and is directly proportional to the mass of the object.
How do you know which object has the greatest inertia?
The more mass an object has, the greater its inertia and the more force it takes to change its state of motion. The amount of inertia an object has depends on its mass – which is roughly the amount of material present in the object.
Which has greater inertia?
The more mass an object has, the greater its inertia and the more force it takes to change its state of motion. The amount of inertia an object has depends on its mass – which is roughly the amount of material present in the object.
What has higher inertia?
Inertia is that quantity which depends solely upon mass. The more mass, the more inertia.
Does a heavier object have more inertia?
Yes, heavier objects have more inertia. It is difficult to move and stop objects with greater mass. The heavier objects will resist change more than the lighter objects.
