Question 1

What is the definition of moment of inertia?

Answer 1

The moment of inertia is defined with respect to a specific rotation axis.

Question 2

How is the moment of inertia of a point mass calculated?

Answer 2

The moment of inertia of a point mass is defined as the product of the mass times the distance from the axis squared.

Question 3

What is the general form of the moment of inertia for extended objects?

Answer 3

The general form of the moment of inertia involves an integral.

Question 4

What is the formula for the moment of inertia of a point mass?

Answer 4

I = m * r^2

Question 5

How is the moment of inertia calculated for a collection of point masses?

Answer 5

The moment of inertia is the sum of the individual moments of inertia for the masses.

Question 6

What is the moment of inertia formula for an object with an axis of symmetry?

Answer 6

I = k * m * r

Question 7

What does the moment of inertia depend on for continuous mass distributions?

Answer 7

It requires an infinite sum of all the point mass moments which is accomplished by integration over all the mass.

Question 8

Fill in the blank: The moment of inertia for a collection of point masses is given by I = _______.

Answer 8

Σ(m_i * r_i^2)

Question 9

True or False: The moment of inertia is the same for all axes of rotation.

Answer 9

False

Question 10

What is the relationship between mass and distance in the moment of inertia formula?

Answer 10

The moment of inertia is directly proportional to the mass and the square of the distance from the rotation axis.
