ROTATIONAL MOTION

What is the motion of a rigid body if all its particles move with the same linear velocity?

• Rotational motion
• Oscillatory motion
• Translational motion
• Random motion

What is the direction of angular velocity vector in rotational motion?

• Tangential to the path
• Radially outward
• Along the axis of rotation
• Opposite to linear velocity

What is the angular velocity of a particle on the axis of rotation?

• Zero
• Infinite
• Same as the body's angular velocity
• Undefined

What is the relationship between linear velocity and angular velocity in rotational motion?

• v = ω/r
• v = ω + r
• v = ωr
• v = r/ω

What is the unit of angular displacement?

• Meter
• Second
• Newton
• Radian
