Rotational Dynamics Flashcards
1
Q
What causes a change in the angular (rotational) motion of an object?
A
An unbalanced torque
2
Q
What is the definition of the moment of inertia of an object?
A
A measure of its resistance to angular acceleration about a given axis.
3
Q
What does the moment of inertia depend on?
A
Mass and the distribution of mass about a given axis of rotation
4
Q
What are the units of torque?
A
Nm
5
Q
What is the principle of conservation of angular momentum?
A
The Total Angular Momentum before a collision will equal the Total Angular Momentum after a collision, as long as no external Torques act upon the system.
