ROTATIONAL MOTION

How is angular velocity represented in vector notation?

• θ
• α
• v
• ω

What is the effect of increasing angular velocity on linear velocity of a particle at fixed radius?

• Decreases
• Remains same
• Becomes zero
• Linear velocity increases

How does the linear velocity of a particle relate to its distance from the axis if angular velocity is constant?

• Inversely proportional
• Independent
• Quadratic
• Directly proportional

What is the main reason for using vector representation of angular velocity?

• To make calculations easier
• To reduce dimensions
• To incorporate direction in rotational analysis
• To eliminate angular displacement

Can angular velocity be negative?

• No, never
• Only in space
• Yes, to indicate direction along the axis
• Only if the body shrinks
