ROTATIONAL MOTION

How is the tangential velocity of a particle related to its distance from the axis of rotation?

• Inversely proportional
• Independent of distance
• Exponentially related
• Directly proportional to perpendicular distance

What is the role of CP in the expression ω × CP?

• It measures angular displacement
• It is the force vector
• It represents linear momentum
• It represents the perpendicular distance from the axis

Why does ω × OC equal zero in the derivation of rotational velocity?

• Because OC is zero
• Because ω is zero
• Because they are perpendicular
• Because ω and OC are parallel vectors

What is the physical meaning of the vector ω × r in rotational motion?

• Angular momentum
• Torque
• Centripetal acceleration
• Instantaneous linear velocity of the particle

How does the direction of ω × CP relate to the plane of rotation?

• It is parallel to the plane
• It lies within the plane of rotation
• It is perpendicular to the plane of rotation
• It oscillates in the plane
