## Conceptual - Angular Rotation

Two objects of equal mass are on a turning wheel. Mass 1 is located at the rim of the wheel while mass 2 is located halfway between the rim and the axis of rotation. The wheel is rotating at a constant angular velocity. For each of the following statements select the correct option.

**The radial acceleration of mass 1 ____ the radial acceleration of mass 2.**

Greater Than:Greater Than:

**Equal To:**The tangential acceleration of mass 2 ____ the tangential acceleration of mass 1.**Less Than:**For a given time, mass 2 travels a distance ____ mass 1.**Greater Than:**The speed of mass 1 is ____ mass 2.**Equal To:**For a given time, the angle covered by mass 2 is ____ mass 1.**Less Than:**The moment of inertia of mass 2 is ___ the moment of inertia of mass 1. (Both moments of inertia are taken about the axis of rotation.)## Discussion

can someone please let me know which ones i got wrong. i

cant seem to figure this one out. thanx

For a given time, mass 2 travels a distance LESS THAN mass 1.

The tangential acceleration of mass 1 GREATER THAN the

tangential acceleration of mass 2.

For a given time, the angle covered by mass 2 is EQUAL TO

mass 1.

The moment of inertia of mass 2 is LESS THAN the moment of

inertia of mass 1. (Both moments of inertia are taken about

the axis of rotation.)

The radial acceleration of mass 1 LESS THAN the radial

acceleration of mass 2.

The speed of mass 1 is EQUAL TO mass 2.

Greater Than: The radial acceleration of mass 1 ____ the

radial acceleration of mass 2.

Greater Than: The speed of mass 1 is ____ mass 2.

Greater Than: For a given time, mass 1 travels a distance

____ mass 2.

Equal To: For a given time, the angle covered by mass 2 is

____ mass 1.

Equal To: The tangential acceleration of mass 1 ____ the

tangential acceleration of mass 2.

Greater Than: The moment of inertia of mass 1 is ___ the

moment of inertia of mass 2. (Both moments of inertia are

taken about the axis of rotation.)
