Question 1

What is the principle of conservation of angular momentum?

  • Angular momentum can change.
  • Angular momentum remains constant when external torque is zero.
  • Angular momentum is the same as linear momentum.

💡 Hint: Consider conditions when movement is unaffected by outside forces.

Question 2

True or False: Angular momentum and torque are always related in a predictable way.

  • True
  • False

💡 Hint: Think of how push or pull affects rotational speed.

Challenge Problems

Push your limits with challenges.

Question 1

A hollow sphere of radius R and mass M rotates about an axis through its center. Calculate its moment of inertia and discuss how it relates to angular acceleration when a torque is applied.

💡 Hint: Refer back to the definitions of moment of inertia and relate them to torque.

Question 2

Consider a rotating rigid body that experiences an external torque until it reaches a steady angular velocity. Discuss the energy transformations involved.

💡 Hint: Think about how energy flows from mechanical input to the kinetic energy of the body.
