Acceleration of falling cones Investigation

Extracts from this document...

Introduction

Ann Hitchcock 10DJG 10YH Acceleration of falling cones Investigation Planning:- Safety Statement:- To make this investigation safe I will wear sensible shoes, this make sure that I will not fall or trip on the table whilst carrying out the investigation. Prediction:- I predict that the smaller the surface area of the cone the faster it will fall. I know this as the more surface area the cone has the more air resistance there is. I also know this as when I carried out some research on parachutes, I discovered, that the larger the parachute the quicker the forces balanced, making the parachute fall slowly. Also, the smaller the parachute the longer it took for the forces to balance out, making the parachute fall much quicker. When I looked at a person freefalling (standing up) the results were that this also took at long time for the forces to balance out. When I saw the results of a person lying down I could see that the forced balanced out quickly, making the person fall slower. I know that it doesn't matter what weight an object has, it falls at the same acceleration, and lands on the ground at the same time. ...read more.

I will also make sure that I move the piece of card forming the cone around 20? each time, making the surface area of the cone decrease in regular intervals. Obtaining:- Results:- Angle (degrees?) Surface Area (cm) Time (seconds) 1st Time (seconds) 2nd Time (seconds) 3rd Average Time (seconds) Velocity (m/s) 20 297 1.35 1.57 1.44 1.45 1.38 40 279 1.31 1.40 1.50 1.40 1.42 60 262 1.22 1.34 1.19 1.25 1.60 80 244 1.10 1.28 1.19 1.19 1.68 100 227 1.04 1.19 1.12 1.11 1.80 120 209 1.06 0.94 1.03 1.01 1.98 140 192 0.87 0.84 1.00 0.90 2.22 160 174 0.78 0.75 0.91 0.81 2.47 180 157 0.72 0.88 0.72 0.77 2.60 Analysis:- My results show that the bigger the surface area of the cone the slower the cone would fall. This was due to the forces balancing out quicker. The smaller the surface area the quicker the cone would fall, it therefore takes longer for the forces to balance out, causing it to have a higher velocity. Looking at the graph above you can see that it did take longer for the cone to fall with a larger surface area. ...read more.

Conclusion

As well as having more data if this experiment was done again I would extend the experiment to involve weight. I would then try to prove that the weight of the cone would not affect the velocity and time of the cone falling. This would help me determine whether or not I was right about weight not being a factor of affecting the time and velocity. If I was to do this then this would be my experiment then this would be what I would do:- Prediction:- I predict that the weight would not make an impact on the time it takes for the cone to fall, and it's velocity. Equipment:- Plastacine Stopwatch, Metre rule, Piece of card with cone and angles drawn on it. This time the variable I would change would be the weight of the cone. Method:- I would drop the cone with a ball of plastercine in it from a height of 2m. Each time I drop it I would change the weight of the plastercine, repeating this three times each for each different weight, this way I could get an average of the times, making it even more accurate.

    For this reason, I predict that the closer the angle is to 90� the greater the acceleration the ball will have. I know that at 90� gravity is roughly 9.8m.s.-2. By dividing 9.8 by 90 and multiplying it by whatever the angle is, I can effectively get the acceleration of the ball due to gravity.

    There was one result that did not fit the pattern, and was too extreme to be our reaction time. This was the result for 0g on the manually timed weight experiment.
