ROTATIONAL MOTION Quiz

• Opposite to torque
• Perpendicular to torque
• Random direction
• Same as torque direction

• Decreases moment of inertia
• No effect
• Makes it zero
• Increases moment of inertia

• When no force acts
• When moving in circle
• When external torque is present
• When I is constant

• Because it is always zero
• Because torque is parallel
• Because ω is axial
• Because the axis prevents rotational change in that direction

• Linear motion
• Free rotation
• Rotation about a fixed axis
• Translational equilibrium
