Questions and Answers

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)?

v = ω / r (correct)
v = ω - r
v = ω * r
v = ω + r
