TITLE : SIMPLE PENDULUMBANDUL RINGKAS

CHAPTER : CHAPTER 1 : INTRODUCTION TO PHYSICSBAB 1 : PENGENALAN KEPADA FIZIK

Inferens : The time taken for oscilation depends on the length of the pendulumTempoh ayunan bandul bergantung kepada panjang bandul

C1 P1 √

Hipotesis : When the length of the pendulum increase, the period of the pendulum also increaseSemakin panjang bandul, semakin lama tempoh ayunan bandul

C1 P2 √

Aim : To investigate the relationship between the length and the period of a simple pendulumUntuk mengkaji hubungan antara panjang bandul dengan tempoh ayunan bandul

C1 P3 √

Variable : [i] Manipulated : Length of the pendulumPanjang bandul

[ii] Responding : Period of 10 oscilationsTempoh 10 ayunan

[iii] Constant : The mass of the bobJisim ladung

C1 P4 √

Materials :

Apparatus : Retort stand with clamps, stopwatch, proctator, brass bob, metre ruler, 100cm threadand 2 pieces of split corkKaki retort bersama pengepit, jam randik, proktator, ladung, pembaris meter,benang 100 cm, dan 2 keping gabus

Procedures : [a] The apparatus was set-up as shown in figure aboveRadas seperti rajah di atas disediakan

[b] The length of the thread, l = 20cm was measured with metre ruler from thepoint it clamped to the centre of the bobPanjang benang diukur dengan pembaris meter dari titik ia dikepit sehinggatitik tengak ladung

[c] The pendulum oscilated at a small angle of the amplitude≈ 10°Bandul diayun pada sudut yang kecil ≈ 10°

[d] The time, t for 10 completed oscilations was taken twice usnig stopwatchand recorded into a tableMasa, t untuk 10 ayunan lengkap diukur dengan jam randik dan bacaandi rekodkan ke dalam jadual

[e] Step [a] to [d] were repeated for l = 30.0 cm, 40.0 cm, 50.0 cm, 60.0 cmand 70.0 cmLangkah [a] hingga [d] diulang menggunakan l = 30.0 cm, 40.0 cm, 50.0 cm,60.0 cm and 70.0 cm

[f] The data, l, t, T, T2 were calculated and recorded into the table providedData l, t, T, T2 dihitung dan direkodkan dalam jadual yang disediakan

Discussions :

[a] Based on your graph, state the relationship between T2 and IBerdasarkan graf, nyatakan hubungan antara T2 dengan l

The length of pendulum, l (cm) is directly propotional to periods square , T2(s2)Panjang bandul berkadar terus dengan tempoh kuasa dua, T2(s2)

[b] From graph, calculate the gradient of the graph T2 against lDaripada graf, hitung kecerunan graf T2 melawan l

using formula ;menggunakan rumus ;

m = y2-y1x2-x1

m =

=

[c] From graph, determine the period, T when l = 45 cmDaripada graf, hitung nilai T apabila l = 45 cm

From graph,Daripada graf,

T2 = 2.0 s2

Period, T = √

1.414 s

Precautionary : [1] we need to switch off the fan to avoid the experiment being distubedtutup kipas supaya tidak mempengaruhi ayunan bandul
