WebΔx = ( 2v + v 0)t. \Large 3. \quad \Delta x=v_0 t+\dfrac {1} {2}at^2 3. Δx = v 0t + 21at2. \Large 4. \quad v^2=v_0^2+2a\Delta x 4. v 2 = v 02 + 2aΔx. Since the kinematic formulas are only accurate if the acceleration is constant during the time interval considered, we have to be careful to not use them when the acceleration is changing. WebThe simplest mechanical vibration equation occurs when γ = 0, F(t) = 0. This is the undamped free vibration. The motion equation is m u ″ + k u = 0. The characteristic equation is m r 2 + k = 0. Its solutions are i m k r=±. The general solution is then u(t) = C 1cos ω 0 t + C 2sin ω 0 t. Where m k ω 0 = is called the natural frequency of ...
