ROTATIONAL MOTION

What type of motion does a merry-go-round exhibit?

• Translational motion
• Oscillatory motion
• Rolling motion
• Rotation about a fixed axis

What is the condition for a cylinder to roll without slipping?

• Velocity of center is zero
• Angular velocity is zero
• Velocity of point of contact is zero
• Translational velocity is zero

In rolling motion, what causes different points on the body to have different velocities?

• Friction alone
• Gravitational pull
• Combination of translation and rotation
• Air resistance

What is true about the motion of particles in a rigid body undergoing pure translational motion?

• Their velocities differ
• They remain stationary
• They all move with the same velocity
• They move in circles

What distinguishes rotational motion from translational motion?

• All particles move with same speed
• Motion is always linear
• Different particles have different velocities in rotation
• No velocity is involved
