ROTATIONAL MOTION

What type of motion does a ceiling fan exhibit?

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

Which of the following is NOT a characteristic of rotational motion?

• Particles move in circles
• Angular velocity is common
• All particles have the same linear velocity
• Axis may be fixed or moving

What is the significance of angles α1, α2, α3 in the figures?

• They measure temperature
• They show mass distribution
• They indicate time
• They indicate change or constancy of orientation

In combined motion, how do the velocities of center of mass and another point compare?

• They are always equal
• They cancel each other
• They are different
• They are perpendicular

What is the condition for a body to have pure translational motion?

• Different velocities
• Zero acceleration
• All particles have the same velocity
• Variable mass
