How can you calculate the period of the oscillation? Important? What approximation is need? What kind of equation do you need to solve? T = 2 s = so sin(wt + Qo) g How do experimental errors (especially in measuring) influence the results? What do you expect to be the main contributor to errors? What causes a pendulum to oscillate back and forth when it is deflect from its resting position and then release? Why is the period of oscillation independent of the mass? A thread pendulum carries out 6 oscillations with an amplitude of 3 cm in half a minute. O Calculate the frequency and the period duration! Draw the y-t-diagram for two periods! How large is the deflection after 4 s?
