ROTATIONAL MOTION

In rotational motion, what is the plane of the circle described by particle P2?

• Parallel to the axis
• At 60 degrees to the axis
• Random
• Perpendicular to the axis of rotation

What is the orientation of the axis of rotation for a spinning top at any instant?

• It is horizontal
• It is vertical only
• It passes through the fixed tip
• It is random

What is the motion of the pivot point O in an oscillating fan?

• It moves in a circle
• It oscillates with the blades
• It remains fixed in position
• It vibrates rapidly

In rotational motion, what is the path of a particle at a distance r from the axis?

• A straight line of length r
• A sphere of radius r
• A square of side r
• A circle of radius r

What type of motion does a top exhibit when spinning in place with its tip fixed?

• Pure translation
• Simple harmonic motion
