Pendulum Investigation

Information

A pendulum will make a repeated swing, which takes a set time. One complete swing is called an oscillation. The time taken for one complete oscillation is called the time period, which is measured in seconds.

                                                                       

                                       One complete swing

Aim

The aim of this investigation is to find out how changing the mass of a pendulum effects the time period of the pendulum.

Variables

The possible variables for this experiment could be;

 Mass of the plasticine.

 Height of the pendulum.

Join now!

 The angle at which the pendulum is released.

We could keep this experiment a fair test by changing only one variable at any one time.
