ROTATIONAL MOTION

What is the significance of the equation ω² = ω₀² + 2α(θ − θ₀)?

• It gives angular displacement directly
• It calculates time of rotation
• It relates angular velocity and displacement without time
• It defines angular acceleration

In rotational kinematics, what is the meaning of θ in the equation θ = θ₀ + ω₀t + ½αt²?

• Initial angular position
• Average angular displacement
• Angular position at time t
• Total angular distance

If a wheel starts from rest and rotates with constant angular acceleration, how does its angular velocity change with time?

• It decreases exponentially
• It remains constant
• It increases linearly with time
• It increases quadratically with time

What does a positive angular acceleration indicate?

• The body is slowing down
• Rotation is clockwise
• The body is speeding up in the positive rotational direction
• There is no rotation

How is angular velocity related to the rate of change of angular displacement?

• ω = θ²/t
• ω = dθ/dt
• ω = θ·t
• ω = Δt/Δθ
