Is rotational inertia the same as moment of inertia?
Yes, rotational inertia is the same as moment of inertia. Both terms refer to the resistance of an object to changes in its rotational motion.
What is the is the measure of an object's resistance to a change in its rotational motion about an axis called?
The measure of an object's resistance to a change in its rotational motion about an axis is called inertia. It is similar to an object's resistance to a change in its linear motion, but it specifically refers to rotational motion. The greater an object's inertia, the more difficult it is to change its rotational motion.
What is the difference between moment of inertia and rotational inertia, and how do they relate to each other in the context of rotational motion?
Moment of inertia and rotational inertia are essentially the same concept, referring to an object's resistance to changes in its rotational motion. Moment of inertia is the term commonly used in physics, while rotational inertia is a more general term that can also be used. In the context of rotational motion, both terms describe how the mass distribution of an object affects its ability to rotate. The moment of inertia or rotational inertia of an object depends on its mass and how that mass is distributed around its axis of rotation. In summary, moment of inertia and rotational inertia are interchangeable terms that describe the same physical property of an object in rotational motion.
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.
Physical quantity coressponding to inertia is rotational motion?
The physical quantity corresponding to inertia in rotational motion is moment of inertia. Moment of inertia is a measure of an object's resistance to changes in its rotational motion. It depends on both the mass and distribution of mass in an object.
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
Is the rotational inertia of your leg greater when your leg is bending or straight?
The rotational inertia of your leg is greater when your leg is straight because the mass is distributed further away from the axis of rotation. When your leg is bending, the mass is closer to the axis of rotation, resulting in a lower rotational inertia.
Is rotational inertia the same as moment of inertia?
Yes, rotational inertia is the same as moment of inertia. Both terms refer to the resistance of an object to changes in its rotational motion.

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.
What is the difference between rotational inertia and moment of inertia, and how do they relate to each other in the context of physics?
Rotational inertia and moment of inertia are terms used interchangeably in physics to describe an object's resistance to changes in its rotational motion. Rotational inertia specifically refers to an object's resistance to changes in its rotational speed, while moment of inertia refers to an object's resistance to changes in its rotational motion due to its mass distribution. In essence, moment of inertia is a more specific term that quantifies rotational inertia. Both concepts are crucial in understanding how objects move and rotate in the context of physics.
What is the relationship between disk rotational inertia and the speed at which a disk spins?
The relationship between disk rotational inertia and the speed at which a disk spins is that the rotational inertia of a disk affects how quickly it can change its speed when a torque is applied. A disk with higher rotational inertia will spin more slowly for a given torque, while a disk with lower rotational inertia will spin faster for the same torque.
Why moment of inertia of hoop is greater than disc?
The moment of inertia of a hoop is greater than that of a disc because the mass of a hoop is distributed farther from the axis of rotation compared to a disc. This results in a larger moment of inertia for the hoop, which is a measure of its resistance to changes in its rotational motion.
Why does the moment of inertia increase when mass is distributed farther from the center of a rotating object?
The moment of inertia increases when mass is distributed farther from the center of a rotating object because the mass is located at a greater distance from the axis of rotation. This results in a larger rotational inertia, making it harder to change the object's rotational motion.
