Convert the following equation in Linear Motion to Rotational Motion: v_avg = s_f - s_i / t_f - t_i

• w_avg = s_f - s_i / t_f - t_i

• w_avg = θ / t

• w_avg = w_f - w_i / t_f - t_i

• w_avg = θ_f - θ_i / t_f - t_i

Choose the correct equations that relation Linear Motion and Rotational Motion

• s = rθ

• s = vw

• v = rw

• a = rα

Convert the following equation in Linear Motion to Rotational Motion: a_avg = v_f - v_i / t_f - t_i

• α_avg = v_f - v_i / t_{f -} t_i

• α_avg = a_f - a_i / t_f - t_i

• α_avg = w / t_f - t_i

• α_avg = w_f - w_i / t_f - t_i

What is the correct equation of instantaneous velocity & instantaneous acceleration? (Please choose the correct parring; Linear Motion : Rotational Motion)

• v_avg = s_{f -} s_i / t_f - t_i ; w_avg = θ_f - θ_i / t_f - t_i

• v = ds / dt ; w = dθ / dt

• a = dv / dt ; α = dw / dt

• v = dv / dt ; w = dw / dt
