Consider an axially symmetric object that experiences no external forces and initially rotates about its symmetry axis. The object then changes its shape while remaining axially symmetric. Afterward, it is found that its moment of inertia about the symmetry axis has increased. How have its kinetic energy T and angular velocity \omega changed?
Answer Choices
A. T has decreased, and \omega has decreased.
B. T has decreased, and \omega stays the same.
C. T stays the same, and \omega has decreased.
D. T has increased, and \omega has increased.
E. T has increased, and \omega stays the same.
