Topic : A Simple Pendulum_______

ProblemEn Hassan take his two son Amir and Alin go to Taman Jubli Perak. Amir playa long swing and his brother Alin play with a short swing(Buaian). En Hassanfnd out that time taken to swing is dierent. !ou are ask to help En Hassanto understand this situation.

"En Hassan dapati buaian yang talinya pan#ang berayun lebih lama$

Aims%. To measure the period o& os'illation o& the simple pendulum. To determine the relationship between the period o& os'illation andthe length o& the pendulum

ApparatusEle'troni' stopwat'h (or me'hani'al stopwat'h or wrist wat'h) retortstand pendulum bob metre rule

Materials*ong thread split 'ork

Procedure and Observations%. +et up the apparatus as shown in

,ig.%.% as &ollows-. Ad#ust the length o& the thread to / 'm.

0. Pull the pendulum bob to one side at anangle o& about %//&rom the 1erti'al.2elease and let the pendulum swing &or a while.

. A&ter a &ew swings start the stopwat'h.2e'ord the time &or the pendulum to make %/os'illations.

3ne os'illation is the time taken &or the pendulumto swing &rom one end (A) to the other (B) andba'k to the original end (A).

The time taken to make one 'omplete os'illation is 'alled the period o&os'illation.

4. 5ow in'rease the length o& the thread to 6/ 'm. 2epeat steps 0 and .
