ROTATIONAL MOTION

What type of motion does a rolling cylinder exhibit on an inclined plane?

• Pure rotational motion
• Pure translational motion
• Vibrational motion
• Translational plus rotational motion

What is the velocity of the point of contact of a cylinder rolling without slipping on an inclined plane?

• Equal to the center's velocity
• Twice the center's velocity
• Half the center's velocity
• Zero

What happens to the velocity of different points on a cylinder rolling down an inclined plane?

• All points have the same velocity
• Velocities are zero
• They have different velocities
• Velocities decrease uniformly

What characterizes pure translational motion of a rigid body?

• Particles move in circular paths
• Particles have different velocities
• All particles have the same velocity at any instant
• Only the center of mass moves

Which type of motion is exhibited by a block sliding down an inclined plane without any sidewise movement?

• Rotational motion
• Oscillatory motion
• Pure translational motion
• Random motion
