Rotational Motion: Why Does External Torque Affect Axis?

Click For Summary
SUMMARY

The discussion centers on the principle of rotational motion, specifically addressing the misconception that a body only rotates about its center of mass when an external torque is applied. It is established that rotation can occur about any axis, not solely the center of mass, depending on the distribution of mass and the application of torque. The conversation emphasizes the importance of understanding the role of external torque in influencing the rotational dynamics of a body.

PREREQUISITES
  • Understanding of rotational dynamics
  • Familiarity with torque and its effects on motion

Why does a body always rotate about an axis through the center of mass only when an external torque is applied to it?
