The equations of rotational kinematics are the same as the equations of linear kinematics, with appropriate substitutions:

x ---------->θ
v ---------->ω
a ---------->α (must be constant)

Equations:

Δx = v_ot + 0.5at² ----------> Δθ= ω_ot + 0.5α t²
v = v_o+at --------------------> ω = ω_o + α t
v² = v_o² + 2aΔx----------->ω² = ω_o² + 2αΔθ
