A circus acrobat while performing spins brings his limbs closer to the body. Due to this
  • a)
    Moment of inertia increases and angular velocity increases
  • b)
    Moment of inertia decreases and angular velocity decreases
  • c)
    Moment of inertia increases and angular velocity decreases
  • d)
    Moment of inertia decreases and angular velocity increases
Correct answer is option 'D'. Can you explain this answer?

While in the pike position the body decreases in radius as each segment moves closer to the axis of rotation, resulting in angular velocity increasing and a decrease of moment of inertia. Thus, during a dive, angular momentum is constant meaning that moment of inertia is inversely proportional to angular velocity.

Angular momentum=moment of inertia×angular velocity
if angular momentum is constant then moment of inertia and angular velocity are inversely related..
moment of inertia depends upon mass distribution..if a spining man brings his arms close to his body in order to decrease moment of inerta and incease angular velocity and spins at faster rate. HOPE IT HELPS!!

Option [d] becoz-->
A circus acrobat while performing spins brings his limbs closer to the body.....Due to this Angular Momentum is conserved but K.E. is not conserved.....Becoz when the moment of inertia decreases, rotational kinetic energy increases as work is done in decreasing the moment of inertia of the body.
