Investigating factors hich affect the period time of a simple pendulum

Investigating factors which affect the period time of a simple

pendulum

Planning

Definitions: Oscillation : Repeated motion of pendulum (to and for)

Period (T) : Time taken for one full oscillation

In this investigation, I am going to experimentally determine a factor which

will affect the period of a simple pendulum and the mathematical relationship

of this factor. This type of pendulum will consist of a mass hanging on a length

of string.

Factors which affect the period (T) of a pendulum:

- Length (L) of pendulum

- Angle of amplitude

- Gravitational field strength (g)

- Mass of bob

I predict that the period will be affected by the length of the pendulum. An

increase in length will produce an increase in time. I based by prediction on

the scientific theory I found in a physics text book:

The pendulum is able to work when the bob is raised to an angle larger than

the point at which it is vertically suspended at rest. By raising the bob,
