I am a high school physics student and I am studying energy and motion. I have to make a procedure for a lab.?

Question

The hypothesis is "Only the length of the pendulum has any significant effect on the period of the pendulum. the amount of mass hung from the end of the pendulum and the distance pulled back has little effect on the period, when compared to the length.
Eqipment: a support stand, support bar from which masses will be hung, 6 14-gram rubber masses with metal hooks that will be hung from a loop tied to one end of the string, a piece of string (1.5-2m), stop watch, protractor to measure the angle, and a meter stick

Answer 1

Hi Iman Perk!
First you will hang the pendulum bar to the support bar and then apply some small force, to make it vibating horizontally that means parallel to the earth. The vibrations must and should be small. Then u observe the vibrations from one end to another end. And one end u start the stop watch and calculate the time taken for 'n' ossilations (say 20). Then u will calculate the time period by the following formulae.
Time period : T=Time taken for n-ossilations/no. of ossilations(ie.n)
Now use the formula which is given by me in the source list.
If you have any more doubt then verify the web:

The procedure is in my knowledge.

Answer 2

So, what's the problem? Your hypothesis already outlines the three things you need to check out.
