ROTATIONAL MOTION

If a rigid body rotates with constant angular velocity, what type of motion do its particles undergo?

• Non-uniform circular motion
• Oscillatory motion
• Linear motion
• Uniform circular motion

What is the angular displacement for half a revolution?

• 2π radians
• π/2 radians
• π radians
• 90 degrees

What is the role of the right-hand rule in rotational motion?

• To measure angular speed
• To stop rotation
• To determine the direction of the cross product
• To calculate time period

How does the linear velocity of particles vary with their angular velocity if radius is constant?

• Inversely proportional
• No relationship
• Quadratically proportional
• Directly proportional

If the angular velocity of a body doubles, what happens to the linear velocity of a particle at a fixed distance from the axis?

• It halves
• It remains the same
• It quadruples
• It doubles
