physics 03-05 moment of inertia
dynamics of rotational motion
newton’s second law for rotation
______
α is in ______
i = mr² → moment of ____ of a ____
moment of inertia (i) measures how much an ____ wants to keep __ (or not start ____)
use ______ to find i = σmr²
unit: ______

name: ______
period 2

Explanation:

1. Newton's Second Law for Rotation states the relationship between torque, moment of inertia, and angular acceleration.
2. The moment of inertia formula for a point mass is defined, and its physical meaning describes rotational inertia.
3. The method to calculate total moment of inertia for multiple masses and its standard SI unit are based on rotational physics definitions.

Answer:

• Newton's Second Law for Rotation: $\tau = I\alpha$
• Moment of Inertia ($I = mr^2$): Moment of Inertia of a point object
• Moment of Inertia ($I$) measures how much an object wants to keep rotating (or not start rotating)
• Use summation to find $I = \sum mr^2$
• Unit: $\text{kg} \cdot \text{m}^2$ (kilogram-meter squared)
