ROTATIONAL MOTION

What is the motion of a rigid body if it moves such that every point has the same displacement?

• Rotational motion
• Rolling motion
• Pure translational motion
• Oscillatory motion

What happens to the velocity of a point on a rotating body as its distance from the axis increases?

• It decreases
• It remains constant
• It becomes zero
• It increases

What is the motion of a wheel moving on a road with pure rolling?

• Only translational
• Only rotational
• Vibrational
• Translational plus rotational motion

What is the role of friction in rolling without slipping?

• It stops the motion
• It reduces speed
• It provides the necessary torque for rotation
• It has no role

What is the main characteristic of rotational motion about a fixed axis?

• All particles move in straight lines
• Particles move randomly
• All particles move in circular paths in planes perpendicular to the axis
• Particles do not move
