ROTATIONAL MOTION

What does the symbol α represent in rotational motion?

• Angular displacement
• Angular velocity
• Angular acceleration
• Torque

What does the symbol ω represent in rotational motion?

• Angular displacement
• Angular acceleration
• Linear velocity
• Angular velocity

How is angular displacement related to linear displacement in circular motion?

• s = r²θ
• s = θ/r
• s = rθ
• s = ωt

What is the role of θ₀ in rotational kinematics?

• It is final angular position
• It is average angular velocity
• It is angular acceleration
• It is the angular position at t = 0

Which of the following is NOT a rotational kinematic equation?

• ω = ω₀ + αt
• θ = θ₀ + ω₀t + ½αt²
• v = rω
• ω² = ω₀² + 2α(θ - θ₀)
