Angular Kinematics Simulation

Angular Kinematics Simulation

This simulation demonstrates the derivation of angular motion equations from first principles for uniformly accelerated rotation.

Initial angular velocity (ω₀): 2 rad/s
Angular acceleration (α): 1 rad/s²
Current angular velocity (ω): 2 rad/s
Angular displacement (θ): 0 rad

Derivation of Eq. (7.38) from First Principles

Given: Angular acceleration is uniform (constant)

dω/dt = α = constant

Step 1: Integrate to find angular velocity

ω = ∫α dt + C = αt + C

Step 2: Apply initial condition at t = 0, ω = ω₀

ω₀ = α(0) + C ⇒ C = ω₀

Final Equation:

ω(t) = ω₀ + αt

Extension to Angular Displacement

Using the definition ω = dθ/dt, we can integrate Eq. (7.38) to get angular displacement:

θ(t) = θ₀ + ω₀t + ½αt²

This derivation and the derivation of other angular motion equations are left as exercises.
