ROTATIONAL MOTION

What is the significance of the fixed axis in rotational motion?

• It increases the speed
• It reduces friction
• It defines the centers of all circular paths
• It has no significance

What is the path of the axis of a spinning top during precession?

• Straight line
• Circular path only
• Spiral
• Conical path

What is the motion of the blades of a pedestal fan when it is turned on and oscillating?

• Only oscillatory motion
• Only translational motion
• Rotational motion about an oscillating axis
• No motion

In rotational motion, what is the direction of the axis relative to the plane of motion of a particle?
