The Spinners Investigation.

Extracts from this document...

Introduction

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

Conclusion

There was one result that didn’t fit into the pattern but I didn’t worry too much about it as I had the 2nd and 3rd result to make sure the average wasn’t messed up.  Also I believe it was just the slow reactions of my partner, starting the stop clock too late after I had dropped the spinner.

If I was to repeat this experiment again I would probably try and get a higher height to drop my spinner from I think that would probably improve my results the measurements wouldn’t be so small if the height was bigger and that way the graphs would look better and be easier to read.  I could also try making spinners out of different materials and see if that affects the time taken to reach the floor any differently.

If we use the wrong data and unsuitable equations, the period and the gravitation acceleration we obtained will be wrong. To avoid such serious error, we ensure the bob is on the same plane as vertical before the experiment starts.

2. Solenoid Investigation

When the resistance of the variable resistor was at its smallest the current through the solenoid was 3.42A with a 2V supply (a 2V supply was found adequate as higher e.m.f. was found to trip the power supply). However, at this current flow, it was found that the solenoid would heat up very quickly and to a high temperature.
