ROTATIONAL MOTION

How is angular displacement of the whole body determined in rotational motion?

• By averaging all particles
• By measuring center of mass
• By measuring θ of any particle
• By measuring velocity

What is the initial condition used in Example 6.10 to find the integration constant?

• At t = 0, θ = 0
• At t = 0, ω = 0
• At t = 0, ω = ω₀
• At t = 1, ω = ω₀

In Example 6.10, what is assumed about angular acceleration?

• It is zero
• It is increasing
• It is constant
• It is variable

Which equation connects angular velocity, angular acceleration, and angular displacement without time?

• ω = ω₀ + αt
• ω² = ω₀² + 2α(θ - θ₀)
• θ = ωt
• α = dω/dt

Which equation is used to find angular displacement when initial angular velocity, time, and angular acceleration are known?

• θ = ωt
• θ = θ₀ + ω₀t + ½αt²
• θ = αt²
• θ = ω₀t
