The moment of inertia is a property that tells us how a rotating object resists the change in angular acceleration. The theoretical background assumes mass, the distribution of this mass relative to the axis, and the selected axis itself for the three parameters. The mass and how far away from the axis it lies give an object a higher moment of inertia. For instance, a hollow ring has a greater moment of inertia than an equivalent solid disc of the same mass and radius because its mass is distributed further from the axis. However, the moment of inertia is independent of the angular velocity of the object. Angular velocity explains how fast an object is spinning, but this does not contribute to the intrinsic resistance to its rotation. It means that irrespective of whether it is spinning rapidly or slowly, the moment of inertia remains unchanged because it only depends on its physical structure and the axis about which it rotates.

What is the angle between the velocity and acceleration of a projectile at its highest point?
At the highest point of a projectile's motion, the velocity is horizontal, and the acceleration (gravity) is vertical. Hence, the angle between them is 90°.

Determine the ratio of moments of inertia between a circular ring and a circular disc with equal masses and radius using a comparison of their rotation behavior about an axis passing through the center and perpendicular to the planes of the bodies in question.
The moment of inertia of a circular ring depends entirely on its mass being concentrated at its outer edge. For a ring, all the mass is at the same radius, making its moment of inertia proportional to the square of the radius multiplied by its mass.
On the other hand, a circular disc has all of its mass distributed along its entire surface. Some of its masses are closer to the axis of rotation than if all the mass had been concentrated to the outer edge of the disc. Thus its moment of inertia will be lower compared to that of the ring. The result of the moment of inertia in a disc comes from considering its mass distribution:.
Comparing both, the moment of inertia of the ring is twice that of the disc for the same mass and radius. Thus, the ratio of their moments of inertia is 2:1, with the ring having the larger value.
