How would a spinning disk and kinetic energy change if its moment of inertia were five times larger but its angular speed were five times smaller?
If the moment of inertia is five times larger while the angular speed is five times smaller, then the kinetic energy of the spinning disk would decrease. This is because kinetic energy is directly proportional to both the moment of inertia and the square of the angular speed. The decrease in angular speed would have a greater impact on reducing the kinetic energy compared to the increase in moment of inertia.

What is the size of inertia when mass gets smaller?
Inertia decreases as mass gets smaller. Inertia is a measure of an object's resistance to changes in its state of motion, and is directly proportional to mass. As mass decreases, so does the inertia of the object.
Why is moment of inertia of a solid disc smaller than that of a ring?
Moment of inertia depends upon the distribution of mass with respect to the axis of rotation.The greater the distance between the bulk of an object's mass and the axis of rotation, the greater the moment of inertia will be. A solid disk has its mass distributed evenly across its diameter, while a ring has its mass concentrated furthest from the centre of rotation.
If you triple your distance from an object what happens to its angular size?
If you triple your distance from an object, its angular size will appear smaller. This is because angular size is inversely proportional to distance – as distance increases, angular size decreases.
The smaller the mass of an object the blank it's inertia?
The smaller the mass of an object, the lower its inertia. Inertia is the resistance of an object to changes in its state of motion, so objects with less mass require less force to accelerate or decelerate compared to objects with more mass.

Does something in space need to be spinning to have gravity?
A spinning object does not create gravity. But it does create centripetal forces (also previously known as centrifugal forces) whereby an object traveling the path of a spinning object is propelled toward the outside wall of the spinning object, due to the force angled to the rotation of the circle counteracting the force of the smaller object traveling tangent to its path. The strength of this force is often measured in "G's". A "G" is equivalent to the force of gravity, ie: 2 "G" is equivalent to twice the force of gravity.
What As a celestial object moves farther away from the viewer it will appear .?
It will look dimmer and dimmer. Also, smaller and smaller (the angular diameter gets to be smaller and smaller).

Is it true that the larger the mass the smaller interia?
no. Inertia is directly proportional to mass. So twice the mass, twice the inertia, etc. So, the larger the mass, the greater the inertia.

Large gas cloud can collapse to become a much smaller spinning disk of gas and What law explains why the center of the cloud becomes so much hotter as the cloud shrinks in size?
As the gas cloud collapses, conservation of angular momentum causes it to rotate faster and flatten into a disk due to conservation of angular momentum. The increase in temperature at the center is due to gravitational potential energy being converted into kinetic energy as the cloud shrinks in size, leading to increased collisions between gas particles and the generation of heat at the core.

What is the relationship between the length of a pendulum and its angular acceleration?
The relationship between the length of a pendulum and its angular acceleration is that a longer pendulum will have a smaller angular acceleration, while a shorter pendulum will have a larger angular acceleration. This is because the length of the pendulum affects the time it takes for the pendulum to swing back and forth, which in turn affects its angular acceleration.
What is the moment of inertia of a hoop and how does it affect the rotational motion of the hoop?
The moment of inertia of a hoop is a measure of its resistance to changes in its rotational motion. It depends on the mass distribution of the hoop. A hoop with a larger moment of inertia will require more force to change its rotation speed compared to a hoop with a smaller moment of inertia. This means that a hoop with a larger moment of inertia will rotate more slowly for a given applied torque, while a hoop with a smaller moment of inertia will rotate more quickly.
