ROTATIONAL MOTION

Which equation is obtained by integrating angular velocity with respect to time?

• α = ∫ω dt
• θ = ∫ω dt
• ω = ∫θ dt
• θ = ∫α dt

Which of the following equations is analogous to v = v₀ + at in rotational motion?

• θ = θ₀ + ω₀t
• ω = αt
• ω = ω₀ + αt
• ω = 2πf

What happens to angular velocity if angular acceleration is zero?

• It increases
• It decreases
• It becomes zero
• It remains constant

How is angular acceleration related to angular velocity?

• α = ω/t
• α = dω/dt
• α = θ/t²
• α = v/r

What is the significance of uniform angular acceleration in rotational kinematics?

• It makes angular velocity zero
• It stops the motion
• It allows use of standard kinematic equations
• It changes the axis of rotation
