Today we did an experiment on the Pendulum , its our very first time trying out this experiment .
It looks something like this .
First , we had to measure the length of the string , from the center of the pendulum to the base of the cock.
One Period of oscillation is the time it takes the pendulum to travel the arc ABC . One beat is equal to half the period of oscillation or the time it takes the pendulum to travel the arc AB or BC
We had to time one oscillation of the pendulum , we had to do that step 3 times so the results would be accurate .
Then We were given a plasticine to wrap the pendulum , to find out if the weight of the pendulum increased , will the oscillation of the pendulum be shorter . We then had to draw a table to record all the readings down , then take the average and find one period of the pendulum . I did not fill in that part , then i handed it up since i did not know how to do , but now , although im not sure if this is the correct method , to find the period of the pendulum , take the average time of 10 oscillations and divide it by 10 .
