Question

Which of the following is the correct expression of moment of inertia?

• A. \(I = m \cdot k^2\)
• B. \(I = m \cdot k\)
• C. \(I = m \cdot k^3\)
• D. \(I = m \cdot k^2\)

Hint:

Understand key rotational dynamics formulas for physics problems.

Answer 1

The Correct Option is A

The formula for moment of inertia is derived from rotational dynamics, where $m$ is mass and $k$ is the radius of gyration.
