Moment of Inertia Flashcards
1
Q
What are the SI units of torque?
A
-Newtons x meter.
2
Q
How many different types of accelerations are associated with an object in circular motion?
A
-two
3
Q
Assume we have a disk and a ring. Both have a mass of M. The disk’s radius and ring’s outer radius are both of length R. Which one, the disk or the ring, has the larger moment of inertia?
A
-The ring.
4
Q
To experimentally determine the moment of inertia of our disk and ring we will use an equation that relates their moments of inertia experimentally to what?
A
-tangential acceleration.
5
Q
When calculating our experimental values for the moment of inertia we use the radius of the step pulley, NOT the radius of the disk or the ring. True or false.
A
-True
