The Spinners Investigation

The prediction for this investigation is the shorter the wingspan of the spinner the faster it will fall the 2.59m to the floor.  I think this because with shortening the wingspan I’m making the surface area smaller this means less air resistance acting upon it when it is falling.  There will be an unbalanced force because gravity will always be the same but the air resistance will get smaller with every half centimetre I cut off, so there will be less area for the air resistance to act upon.

The apparatus you need for this experiment are the following things:

A paper spinner

A paperclip (to give the spinner some weight)

A table to which you can stand on to hold the spinner to the height of 2.59m (the ceiling)

A stop clock

A table to record the results (the results are the times taken to reach the floor)

In order to make the investigation fair:

You will only change the length of the wing span because that is the variable you are using; changing anything else would mean the experiment would be corrupted.  

The things you have to keep the same are the spinner; you will use the same spinner throughout the experiment.  Keep the height the same too.

In this investigation you have to count the time taken for the spinner to fall the 2.59m to the floor from the ceiling and measure the length of the spinner since you change that yourself.  When you drop the spinner you take the time taken for it to land using a stop clock, you do this three times and take an average.  You can’ get an exact time taken for it to fall but the stop clock is the best instrument for the job as far as I can decide.

The safety issues are important, like when you ...
