Questions and Answers

What is a common characteristic of the rotation of different points on a rigid object?

  • They rotate in opposite directions
  • They rotate about different axes
  • They rotate at different rates
  • They rotate at the same rate (correct)

    • Which of the following is true about the rotation of a rigid object?

  • The rotation of the object is dependent on the material it is made of
  • The rotation of the object is dependent on the axis of rotation
  • The rotation of the object is dependent on the shape of the object
  • All points on the object rotate at the same rate (correct)

    • What happens to the rotation rate of different points on a rigid object when it rotates about a fixed axis?

  • It decreases as you move towards the axis of rotation
  • It increases as you move towards the axis of rotation
  • It remains the same for all points (correct)
  • It is dependent on the velocity of the object

    Rigid Object Rotation

    • A common characteristic of the rotation of different points on a rigid object is that they rotate at the same rate.
    • When a rigid object rotates about a fixed axis, the rotation rate of different points on the object remains the same.
    • The reason why different points on a rigid object rotate at the same rate is that they are connected and move together as a single unit.
    • The statement that is false about the rotation of a rigid object is that different points on the object rotate at different rates.
