Laporan Amali:
Aim : To understand the steps in scientific investigation.
Apparatus : Electronic stopwatch, retort stand, pendulum bob, and meter rule.
Materials : Long thread, split cork.
Hypothesis : The oscillation period directly proportional to the length of thependulum.
Variables : Which is,
a. Constant: umber of oscillation
Procedure : !. The correct way of using and reading an electronic
stopwatch is learnt from the teacher.
". # simple pendulum of $% cm length is prepared as shownin the diagram.
$. The pendulum bob is swung slightly and the time takenfor !% complete oscillation is observed.
&. The time taken for one complete oscillation is calculated.
'. (tep two and step three are repeated by using deferent pendulum lengths.
). # graph between the pendulum length and oscillation
period is drawn.
