Rotation - Inertia Flashcards
1
Q
What is rotational inertia?
A
The tendency of an object to resist angular acceleration.
2
Q
What is the equation for rotational inertia for a point?
A
I = MR^2
3
Q
What is the equation for rotational inertia for a complex shape?
A
The equation will be provided.
4
Q
How do you determine the rotational inertia of multiple objects?
A
Add them together
5
Q
What is the rotational equivalent of Newton’s 2nd law of motion?
A
α = T / I
6
Q
Which has more rotational inertia, a ring or a solid disc?
A
A ring because more mass is located further away from the axis of rotation.
