What is the relationship between angular displacement (Δθ) and the arc length (s)?
What is the relationship between angular displacement (Δθ) and the arc length (s)?
- Δθ = s - r
- Δθ = s / r (correct)
- Δθ = s + r
- Δθ = s * r
How is angular velocity defined?

- Change in angular displacement per unit of time (correct)
- Rate of change in circumference over time
- Rate of change in radius over time
- Change in arc length per unit of time
What is the relationship between angular velocity (ω) and tangential velocity (v)?
What is the relationship between angular velocity (ω) and tangential velocity (v)?
- v = ω / r (correct)
- v = ω - r
- v = ω * r
- v = ω + r
