# To investigate the amount of time it takes to complete one swing from points A-C.

Extracts from this document...

Introduction

PENDULUM

Introduction

Prediction

### The drawings that I drew on the previous page show that all of the pendulums have the same gravitational energy, as they are all lifted the same height (the drawings show this by lifting up the pendulum every two lines on each drawing).

Conclusion

### I increased the length of the string each time by 10cm every time the pendulum was swung.

To make this a fair test

### To make this a fair test I will have to:

Keep all the variables constant, including the mass and the height.

Only change the length of the string, as this is the variable that I am changing.

Start at 10cm.

End at 100cm.

### To make my experiment accurate I will time how long it takes to time 10 swings and divide it to find out how long it takes for the pendulum to swing 1 swing.

There are two forces acting on the pendulum bob. Gravity tries to pull the bob downwards but this is resisted by the tension in the string. As there are only two forces they can only be balanced when they are in opposite directions.

As the pendulum rises the kinetic energy is transferred back to potential energy. The speed of the pendulum decreases and falls to zero as it reaches the top of its swing, with the potential energy a maximum again. A small amount of energy is lost due to air resistance as the pendulum swings.

Fair testing I will make my testing as fair as I can by firstly, making sure that the windows are closed so there are no elements affecting my pendulum, before I begin the investigation. Secondly, I will then measure the piece of 30cm string and the weight of the pendulum to double check on my first readings.

Investigation Planing I have chosen to investigate how the length of a pendulum relates to the time for one oscillation. I will make a prediction based on the previous scientific knowledge. I will then carry out a pretest to determine the range in which I will measure the pendulum.
