Surfing For Physics Formulas For Velocity?

Mark asks…Physics Formulas Help!?On my formula sheet for angular motion physics, there are equations in one box such as average velocity=theta/time and average angular acceleartion=delta w/delta t. There is also a box with equations such as wf=wi+at. How do I know which formulas to use?Nancy answers:1) average velocity ω = Θ/time = rad/sec ...(being Θ the angle in radians equal to 0.01745*degrees of the angle)
dual formula in translating motion : V = S/t = m/sec
2) accel. A = Δω/ Δt =
