we discussed pendulums today, the general basic things of them.
we used stop watches today to test whether the angle we lift the pendulum affected the time (period) of each oscillation. we discovered.. that the change is very little, unless the angle is less than 20, then it is always the same period 9at least checking with stopwatch)among the class, it was all around 2.4
we did a second thing today, using differently weighted balls tied on the end of strings. using this, we determined whether or not mass was a largely effective factor in changing results. this was disproven, both balls showed a time of approx 1.4
more prac tomorrow to do
