ROTATIONAL MOTION

What is the motion of the axis of rotation in a precessing top?

• It stops rotating
• It moves linearly
• It rotates about a vertical axis
• It disappears

What is the effect of increasing the distance from the axis on the radius of the circular path?

• The radius decreases
• The radius stays the same
• The radius becomes zero
• The radius of the circular path increases

What is the motion of a particle at a distance r1 from the axis in rotational motion?

• Linear motion of length r1
• Oscillation of amplitude r1
• Circular motion of radius r1
• Random motion within radius r1

What is the motion of the point C1 in Fig. 6.4?

• It moves in a circle
• It oscillates
• It is fixed on the axis
• It drifts with time

In rotational motion, what is the relationship between the axis and the center of the circle for any particle?

• The center is above the axis
• The center is below the axis
• The center lies on the axis
• The center is outside the body
