Helicopter Investigation

Easily established, the sycamore tree produces sycamore seeds. These seeds are of an extremely strange looking seed, I say this because the seeds when in the air they spin like tiny helicopters. Due to the spinning they are kept in the air for a longer amount of time.

Aim

*In this investigation I have been asked to find out how long it takes for a paper helicopter to fall 2 metres. After doing this I shall investigate other ways of changing the timing of its landing.

I shall do this by using a range of variables. These include of:

• Length of wings
• Number of tails

*I have chosen to use the variable of the number of paperclips being added to the tail of the paper helicopter that I shall make.

I have chosen to change this variable because I know that gravitation is the effect of the gravitational force of attraction, which acts between all objects in the universe. For example it is widely noticed with massive objects like the planets. The planets remain in orbit because of gravitational force of attraction.

The gravitational force, which pulls the object downwards, is called the weightof the object.

Isaac Newton stated that there is a gravitational force of attraction between any two objects with mass, which depends on their masses, and the distance between them.

I think with this

Middle

The cutting of course will be done with a pair of scissors.

After they are cut out and folded along, some may find it better and more presentable if they are to be decorate and colour in their paper helicopters!

What else is involved in this investigation? Once all of the above has been done we are to set up our equipment out. Having set out the timer, paperclips, and paper helicopter in front of me, I am to make sure that I have drawn out a results table, which I will record the timings down in. (As shown in the results table.)

I will then ask for a little help for getting the timing at the best time possible. When I went to drop/release the paper helicopter from my hands I realised that I wasn’t actually in fact dropping/releasing the paper helicopter from 2 metres of height. In fact I was dropping it from my height with my arms being placed right above my head as high as I could manage. So I then made sure to measure how high I was releasing the paper helicopter from, I found that with the heels of my shoe and my arms being stretched up way above my head I was actually releasing the paper helicopter from a height of 2 metres and 3 centimetres. I left the measurement of the height I was releasing the paper helicopter at how it was already, because it was getting to the point where it would be getting very time consuming.

Conclusion

In order to make it a fair test it also meant that safety was to be involved as well, as far as I was concerned not many safety measures had to be taken, I say this because as mentioned earlier no safety goggles were needed, no hair was really in need of being tied back and no safety cloaks were to be worn. The only safety we were to be notified was to tuck in our stools so that no accidents were to be caused as the investigations were being held.

Looking back at my results I don’t really think that there were really any results which were unexpected, there may have been the one or two timings which may have been timed a bit earlier than they should have been but nothing which was really way out of proportion.

If I were to do this experiment again I think that I will definitely make sure that I am to drop the paper helicopter at a height of 2 metres and not 2 metres and 3 centimetres!

I shall aim to achieve more results although I feel that I already have a reasonable amount of timings.

I think that if I were to do the experiment again I would achieve a very similar set of results, as it would only be from the difference of 3 centimetres.
