Most of the data points were on, or very close to, the line of best fit. However, I think that unless I had specialist equipment the results would be distorted because the wire would eventually get very hot. Table 1 Below are the results I have obtained.

Evaluation All of my results fitted my pattern of results. In this investigation I am going to investigate what affect the resistance of a wire. I could have got a friend to time but the results would have turned out relatively similar. Conclusion In conclusion, there is very strong evidence to show that the larger the surface area radius of the parachute the longer it will take to fall to the ground.

I will also control, using the power pack, how many volts pass through the wire. There is no resultant force and the skydiver reaches terminal velocity. In order to provide additional evidence and extend my investigation to find out more and back up my conclusion, I could perhaps get a machine that would drop and time the fall of each parachute.

I will then turn the power pack on and record what voltmeter and ammeter readings. Below is a sample graph graph 1 to show the kind of results I expect to obtain. Discussion Overall, my results are very consistent with my predictions.

I think my method could have been improved to produce results that were even more consistent. The free electrons kee Related. In addition, I will make sure I turn the power pack off after each reading. As the skydiver gains speed, their weight stays the same but the air resistance increases.

I have taken three reading and have worked out the average, shown in red. Although air resistance and gravity will affect the fall of the parachute, I cannot control these factors; however, it will be the same for each experiment so the results should be unbiased.

Variables There are different variables that can be changed in this experiment; these are the independent variable.

I will place one crocodile clip at 0cm on the wire and the other at 5cm to complete the circuit. Below is a table showing the effect of changing variables. Another thing I could change is the height I drop the parachutes from and see if this effects the conclusion I have made, also the weight could affect my idea about air resistance.

The variables I will control will be the type of wire resistivity and the cross-sectional area of the wire. This is because the frictional force acting against it is increasing as the speed increases, but is still less than the weight of the object.A series of videos covering the GCSE Physics syllabus for AQA OCR and Edexcel.
