Paper Cake Case Investigation

Planning

P.2a - The Aim

I am going to drop a paper cake case from a height and record the time it takes to fall to the floor.

P8.a – The Prediction

I predict that paper cake cases that fall from a smaller distance will fall at a quicker time. However, the cake cases that fall a greater distance will have a greater speed.

P8.a – The science behind the prediction

Consulted text book of GCSE Bitesize: Falling

I predict that cases falling shorter distances will fall at a quicker time because if an object falls at 1 metre per second, the same object will fall 2 metres in 2 seconds.  This will be positive correlation on a graph.

Speed is measured by Distance

                          Time

I predict that cases travelling further will have a greater speed.  The force due to gravity of the earth becomes greater as you get closer to the core of the earth.  As an object is falling, the force due to gravity increases, increasing the speed of the falling object.

Conclusion

My prediction that cases that fall a greater distance will have a greater speed is supported when it is considered that point 4 is a greater distance on the x axis than point 3 and the speed of point 4 is a greater time on the y axis than point 3.  

My prediction was that a certain distance, the speed would stay equal.  There is no point in my results that the speed stays the same.  I think this is because the paper cake case has a varied speed throughout its fall.  It starts very slow due to air resistance, and then increases the more it falls due to increased pull of force due to gravity.  The terminal velocity is reached after these two stages and so there is no point that we can identify exactly when the terminal velocity was reached.  If a paper cake case goes through these three stages and I have taken the overall time, I do not know at what point the terminal velocity is reached and so although the results are correct, I cannot be sure this result can find if there is terminal velocity reached.

    It was clear from the results of the pre-test that the cup cakes had reached terminal velocity between 4 metres and 5 metres because the speed from this height would not increase anymore so we decided for the main experiment to use a constant height of 4.6 metres.

    I must use the same paper cake case to make it a fair test and I must change the height from which I drop the paper cake case to prove my prediction. Valid Evidence The possible problems I may face with this investigation is that when I let go of

    As there is no way the trolley can go through the slope it has to travel down it. The steeper the slope, the faster the trolley will go because there will be less time taken for the trolley to reach the bottom.

    To make sure the rulers are straight, I will use the spirit level. Then I will measure the time by dropping case from the top. I will repeat the experiment, but this time I will use 2 cake cases instead and then 3 and so on.
