Simple Pendulum

 

Aim: 

To investigate the relationship between the length and period. To determine the acceleration due to gravity (g). 

Theory:          ( The answers to these should be used to construct a paragraph) 

                       What is a pendulum (i.e. the material that makes up a pendulum).

                        What is a period?

                        What are the factors that affect the period of a pendulum?

Apparatus:     

• meter rule
• pendulum
• stopwatch set square
• clamp stand

Diagram:       

                            Simple digrams of the setup of the apparatus used to carry out experiment. 

                                               

Procedure:  (This should be in past tense) 

Set up the apparatus as shown in the diagram with the length, L, of the pendulum at about 80cm, ensure that the rule is vertical. Use the rule and set square to measure the exact length of the pendulum.

Set the pendulum to oscillating with a small amplitude but in one plane

Using the countdown method the timing from mid-reference line, find time, t₁, taken for twenty (20) oscillation.

Repeat timing (t₂) to ensure accuracy.

Change the length of the pendulum and repeat the procedure. Vary the length between     L= 10.0 cm and 80.0 cm. ensure that your readings are spread over the entire range.

 

Results:         



                                                       Place the results in a suitable format.

Calcualtion:  

                                    ALL calcualtions should go in this section 
                                  Graph should be drawn on the graph paper in the SBA book 



Discussion: 

1.      Do a table analysis to find out if T².is proportional to L

2.      Plot a graph of T² against L.

3.      Use your graph to find the period of a pendulum whose length is 35cm.

4.      Find S, the gradient of the graph

5.      Give that g = 4π²/100S

6.      What can you conclude about the relationship between L and T²      

7.      Write an equation connecting T² and L

Starting with what is in red should be in the discussion, also precaution and sources of error should be included and this section is written in paragrah format.

Conclusion:    

                Write a suitable conclusion based on your objective.
