ROTATIONAL MOTION

What is the motion of the center C2 of the circular path of particle P2?

• It moves in a small circle
• It oscillates
• It remains stationary on the axis
• It drifts away

In the case of a spinning top, what is the status of the point of contact with the ground?

• It moves in a circle
• It slides away
• It is fixed
• It vibrates

What happens to the plane of motion of a particle as its distance from the axis increases?

• It becomes parallel to the axis
• It tilts at an angle
• It becomes random
• The plane remains perpendicular to the axis

What is the main characteristic of rotational motion of a rigid body about a fixed axis?

• All particles move in straight lines
• All particles move in the same circle
• Every particle moves in a circle with center on the axis and plane perpendicular to the axis
• Particles move randomly

What is the shape of the path traced by the tip of the axis of a precessing top?

• Straight line
• Parabola
• Helix
• Circle
