ROTATIONAL MOTION

What causes a rigid body to undergo rotational motion when constrained?

• Gravity
• Presence of a fixed axis
• Magnetic field
• Air pressure

What is the nature of motion of a block sliding down an incline without rotation?

• Rotational motion
• Rolling motion
• Pure translational motion
• Oscillatory motion

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

• Maximum
• Equal to ωr
• Half of maximum
• Zero

What is the direction of velocity of a point on a rotating body?

• Radially outward
• Radially inward
• Along the axis
• Tangential to its circular path
