# To investigate the fall of a helicopter, when you change the variables and the change it makes to the time the helicopter takes to fall.

Extracts from this document...

Introduction

## GCSE COURSEWORK

Aim:

To investigate the fall of a helicopter, when you change                                   the variables and the change it makes to the time the helicopter takes to fall.

Variables:

• The amount of paperclips I use
• The size of the paperclips I use
• The height from which the helicopter is dropped
• The different types of paper I can make the helicopter out of (sugar paper, cardboard, plain paper.)

I am going to investigate what difference the amount of paperclips that I attach to the stem will make to the time the helicopter takes to fall. I will use the same type of paper and the same length and width of the stem and wings.

Prediction:

I predict that the more paperclips added to the stem of the helicopter the quicker the helicopter would take to fall. This is because the more paperclips there is, the more weight that is added to the helicopter, so there is more for gravity to pull on, therefore bringing the helicopter to land faster.

Fair Test:

Middle

Get somebody else then to time with a stop clock the time the helicopter to fall from your hands and reach the floor.Then once again repeat it but with 1 more paperclip added to the stem, but making sure that the paperclip is the same size and weight as the other paperclip.Once again time the length of time the helicopter takes to fall from 2 metres and then record it.Repeat this until eventually you have 6 paperclips on the stem of the helicopter and 6 sets of results.

9. Then draw a diagram of the experiment and plot a                 graph.

Observations:

When I did my trial runs I observed the helicopter as it fell, I noticed that it fell quite

Conclusion

I tried to do some more observation as I was adding more paperclips but I got awkward when it was falling so quickly but I did notice that it started to rotate faster, as I added more paperclips so it was accelerating at a quicker speed.

Evaluation:

When I did my experiment nothing went wrong and it all went according to plan, it was quite easy to record, but as u can imagine when it was falling in less than a second you had to be quick to stop the stop clock, so it maybe a few mille seconds out, but it is pretty much 100% accurate.

There was quite a few variables I could of changed the length and width of the stem a wings, but I thought it would have been difficult if I had to remake a helicopter every time and same with different types of paper.

There were no anomalies everything went fine.

If I wanted to extend my experiment I could do it a lot more times using more paperclips but still making sure that they are the same length and width, so as not to make it an unfair test.

I will make sure the board and bench are flat by placing a level on their surfaces. I will use a wooden block to raise the board. I will place the block underneath the board and slowly push it towards the end of the board so that the board is slowly raised.
