Angular Motion Table Flashcards
1
Q
What is Moment of inertia ?
A
Reluctance of a bod to change its state of angular motion or rotation.
2
Q
What is angular velocity ?
A
The rate of spin in a particular direction.
3
Q
What is angular momentum ?
A
The amount of angular motion of a rotating body.
4
Q
What is the calculation for moment of inertia ?
A
Sum of mass multiplied by distance of mass from axis of rotation.
Squared = I=Emr2
5
Q
What is the units of measurement or moment of inertia ?
A
Kgm2
6
Q
What is the unit of measurement angular velocity ?
A
Rad/s
7
Q
What is the unit of measurement for angular momentum ?
A
Kgm2/s
8
Q
What is the calculation for angular velocity ?
A
Angular velocity = angular displacement / time
9
Q
What is the calculation for angular momentum ?
A
Angular momentum = moment of inertia x angular velocity
