ROTATIONAL MOTION

What type of motion is exhibited by a ceiling fan?

• Pure translation
• Oscillation without rotation
• Rotation about a fixed axis
• Random motion

What is the significance of point O in the figures?

• It is the heaviest particle
• It is the geometric center only
• It is the pivot point
• It represents the center of mass of the body

What is the trajectory followed by the center of mass in translational motion?

• Circular orbit
• Random zigzag
• Stationary position
• Translational trajectory (Tr1 or Tr2)

How can you visually distinguish between pure translation and combined motion?

• By the color of the object
• By the sound it makes
• By its weight
• By observing whether the orientation of the body changes

What remains unchanged in pure translational motion of a rigid body?

• The speed of individual particles
• The mass distribution
• The angle between any internal line and a fixed direction
• The temperature of the body
