ROTATIONAL MOTION

What happens to a particle when its perpendicular distance from the axis is zero?

• It moves in a large circle
• It vibrates rapidly
• It remains stationary
• It moves linearly

What is common between the planes of motion of P1 and P2 in rotational motion?

• They are the same plane
• They are parallel to the axis
• They intersect each other
• Both are perpendicular to the axis of rotation

What is the orientation of the circular motion plane for particle P2 in Fig. 6.4?

• Parallel to the z-axis
• Inclined at 30°
• Random
• Perpendicular to the z-axis

In rotational motion, what determines the size of the circle described by a particle?

• Mass of the particle
• Angular acceleration
• Perpendicular distance from the axis
• Time of rotation

What is the trajectory of a particle located exactly on the z-axis during rotation?

• Circular path of radius 1
• Straight line motion
• Stationary point
• Helical path
