  • {‘value’: ‘Rod’, ‘feedback’: ‘Good job!’}

  • {‘value’: ‘Hoop’, ‘feedback’: ‘Think of keeping most of the mass close to the axis of rotation.’}

  • {‘value’: ‘Disk’, ‘feedback’: ‘Think of keeping most of the mass close to the axis of rotation.’}

  • {‘value’: ‘Point Mass’, ‘feedback’: ‘Think of keeping most of the mass close to the axis of rotation.’}
