ROTATIONAL MOTION

What is the primary condition for pure rolling?

• High friction
• Low speed
• No slipping at the point of contact
• Constant mass

What is the effect of increasing angular velocity on a rotating body?

• Decreases rotational inertia
• Stops the motion
• Increases linear velocity of points away from axis
• Reduces radius

What is the motion of a point on the rim of a rotating wheel?

• Linear motion
• Oscillatory motion
• Circular motion
• Random motion

How is the motion of a rolling object best described?

• Pure translation
• Pure rotation
• As a combination of translation and rotation
• Random motion

What is the key feature of a rigid body in pure translational motion?

• Changing speed
• Rotation about center
• Uniform velocity across all particles
• Varying directions
