ROTATIONAL MOTION

How is the direction of ω affected when rotation changes from anticlockwise to clockwise?

• No change
• Becomes zero
• It reverses
• Points sideways

What happens to the angular velocity if the body rotates slower?

• Increases
• Remains same
• Becomes negative
• It decreases

What is the significance of the equation v = ω × r in rotational kinematics?

• It calculates angular displacement
• It measures radius
• It gives both magnitude and direction of linear velocity
• It replaces time

If a particle's distance from the axis is doubled, what happens to its linear velocity if ω is constant?

• It halves
• Remains same
• Quadruples
• It doubles

What is the relationship between the planes of circular motion of different particles?

• They intersect at 45°
• Perpendicular to each other
• All planes are parallel
• Random orientations
