Rotational Mechanics Flashcards
1
Q
Definitions for moment of inertia?
A
- Σmr^2 with m and r defined or I is a measure of the mass and the way the mass is distributed about an axis
- I equal to the product of the mass times distance squared from axis of rotation for each constituent mass.
- a body’s tendency to resist angular acceleration/change in angular speed.
2
Q
Definition for The law of conservation of angular momentum?
A
The (total) angular momentum (of a system) remains constant provided no external torque acts (on the system).
3
Q
What is Angular acceleration?
A
The rate of change of angular velocity.
4
Q
What is angular velocity?
A
The rate of change of angular displacement.
