Worked practice questions

For a cylinder rolling without slipping, the point touching the ground has velocity:

  1. Twice the centre's
  2. Exactly zero
  3. At its maximum
  4. Half the centre's
Show answer and solution

Correct answer: B. Exactly zero

1. No slipping means no sliding at the contact. 2. The contact point is momentarily at rest. 3. So its velocity is zero. _Source: syllabus Physics Part I, Chapter 7, Systems of Particles and Rotational Motion._

The fixed line about which a ceiling fan turns is its:

  1. Radius of gyration
  2. Line of action
  3. Axis of rotation
  4. Centre of mass
Show answer and solution

Correct answer: C. Axis of rotation

1. A pivoted body can only rotate. 2. It turns about one fixed line. 3. That line is the axis of rotation. _Source: syllabus Physics Part I, Chapter 7, Systems of Particles and Rotational Motion._

Torque is the rotational analogue of:

  1. Mass
  2. Speed
  3. Power
  4. Force
Show answer and solution

Correct answer: D. Force

1. Force changes translational motion. 2. Something similar changes rotational motion. 3. That is torque, the moment of force. _Source: syllabus Physics Part I, Chapter 7, Systems of Particles and Rotational Motion._
