ROTATIONAL MOTION

What is the state of motion of the center of mass of a rolling cylinder?

• It remains stationary
• It rotates in place
• It moves with constant translational velocity
• It moves with zero acceleration

What is the state of motion of a point at the top of a rolling cylinder?

• It is at rest
• It moves slower than the center
• It moves at the same speed as the center
• It moves faster than the center

What is the main difference between sliding and rolling motion?

• Sliding is faster
• Rolling involves rotation while sliding does not
• They are the same
• Sliding occurs only on inclines

In which type of motion do all particles of a rigid body follow circular paths?

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

What is the motion of a solid cylinder rolling down an inclined plane called?

• Sliding motion
• Spinning motion
