ROTATIONAL MOTION

What happens to the direction of the angular velocity vector if the sense of rotation changes?

• It remains unchanged
• It becomes zero
• It rotates by 90 degrees
• It reverses

How is the direction of the angular velocity vector determined using the right-handed screw rule?

• Opposite to the direction of screw advancement
• Perpendicular to the screw motion
• Random direction independent of rotation
• In the direction the screw advances when rotated with the body

Along which direction does the angular velocity vector point in fixed-axis rotation?

• Tangential to the path
• Radially outward
• Perpendicular to the plane of motion but not along the axis
• Along the axis of rotation

Is angular velocity a scalar or a vector quantity?

• Scalar
• Pseudoscalar
• Vector
• Dimensionless

What type of motion do individual particles of a rigid body undergo during rotation about a fixed axis?

• Linear motion along the axis
• Oscillatory motion about the axis
• Random motion within the body
• Circular motion in a plane perpendicular to the axis
