Why is it necessary to mention the axis of rectangular bar while calculating the moment of inertia?
An object rotating about its long axis will have a different moment of inertia than when it is rotating about its short axis. A solid disk will have a different moment than a washer, and there are formulas derived for calculating the moments of many common shapes.
Can one object have more than one rotational inertia?
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).
What is the other name of newton's first law?
Another name for Newton's first law is "the law of inertia."
Explain why when you throw a ball it travels in an arc and not in a perfectly straight line?
This is called projectile, because of Earths gravitational pull and their own inertia ,projetile follows a curved path. They have both horizontal and verticals velocities.
What is the SI unit of inertia?
The unit of Inertia is kg and the Moment of Inertia is kg*m^2
Must an object be rotating to have a nonzero moment of inertia?
moment of inertia is basically an objects resistance to its state of motion.
What increase the moment of inertia?
A rotating body that spins about an external or internal axis (either fixed or unfixed) increase the moment of inertia.
What is inertia in a 3 Phase motor?
A motor when running has inertia in the rotating parts, which is a reserve of kinetic energy. The kinetic energy is found as the moment of inertia times the square of the angular velocity.
What moment of inertia does not depend on angular velocity?
An object that is rotating at constant angular velocity will remain rotating unless it is acted upon by an external torque.
What physical characteristic does the moment of inertia of a rotating object most directly and accurately measure?
This is rotational inertia. When inertia forces an object to rotate, it will continue to do so until another force acts upon it.

Inerita is the law of what?
the law of inertia states that:A body will preserve its velocity and direction so long as no force in its motion's direction acts on it.For example : a package thrown out of an airplane will continue to move at the speed of the airplane on the horizontal axis (in the direction of the airplane's movement). Since the law of gravity acts on the package (a vertical downward axis), the package will gather speed along the vertical axis, but on the horizontal axis its speed will remain equal to that of the airplane.
How much moment of inertia require to turn the stationary cylinder into rotating motion?
Moment of inertia opposes turning anything! Besides which, the answer would depend on the mass of the cylinder as well as the which axis which it is meant to rotate around.
Why do you land in the same spot if the earth is rotating?
Inertia. We move along with the Earth. A force would be required to pull us back.
Why does the coasting rotating system slow down as water drips into the beaker?
Ans : By the formula of moment of inertia , I=mr2 (2=square) As by the formula it is clear that the moment of inertia depends on the mass and the radius of a particular body , so as the mass increases moment of inertia will considerably increase , So as the water drips into the beaker the mass of the beaker will increase By the law of conservation of angular momentum Moment of inertia is inversely proportional to the angular velocity ( omega ) , Since in the above case of coasting rotating system moment of inertia is increased so the angular velocity (omega) will also decrease and hence the coasting rotating system will now rotate slowly as compared to its rotation before dripping water !
Why aren't inertia governors are used widely?
Inertia governors are more sensitive than centrifugal type of governors.A small change in the speed of engine introduces large amount of change in the rotating bodies of the governor which are difficult to balance .
What is the constant of proportionality between torque and angular acceleration?
The rotating object's moment of inertia. Similar to Newton's Second Law, commonly quoted as "force = mass x acceleration", there is an equivalent law for rotational movement: "torque = moment of inertia x angular acceleration". The moment of inertia depends on the rotating object's mass and its exact shape - you can even have a different moment of inertia for the same shape, if the axis of rotation is changed. If you use SI units, and radians for angles (and therefore radians/second2 for angular acceleration), no further constants of proportionality are required.
