Introduction

Experiment to Investigate the Relationship between the Braking Distance of a Toy Car and the Height of the Ramp.

Planning

To carry out this experiment safely I will ensure that the necessary safety precautions are taken place. Goggles and lab coats should be worn during the experiment. All likely safety hazards are eliminated. I will make sure the ramp is placed on the table in a stable manner and that I will ensure that the ramp is not too high.

        The procedure of this experiment is to first get a ramp of suitable length, and place onto the bench. Raise height by using a retort stand, by placing it under the ramp, moving it backwards and forwards to adjust the height. Produce a range of heights to which to use, and once all set it all up.

Conclusion

Evaluating

        I think the experiment went very well. The procedure and the manner of which the experiment was taken went smoothly with a few anomalous results. However I feel that the results were not very reliable as there were a few problems with the experiment procedure. The problems were as the car went down the ramp it swerved in different directions, which may have made the results misleading. I therefore suggest that a trolley would be used instead of a toy car. With this in mind, the results still prove the prediction right, therefore showing that as the height of the ramp increases, as does the braking distance. Also one could measure the length of the ramp, and use a timer and measure the time taken for the car or trolley to stop after release from the top of the ramp.

    gh = 1/2v2 Note: Also at that point all the GPE would have already changed to KE. Since it is parallel to the table, therefore h=0, and if h=0 then "v=0" At the moment it leaves the ramp it will move freely under gravity causing only a downward acceleration.

    We used the same person to measure the heights each time, the same person to use the stop clock and also the same person to send the trolley down the ramp. We did each experiment five times and worked out the average.

  2. What affects the stopping distance of a toy car

    It may be that when I double the height of the ramp, I double the G.P.E, which then doubles the time for the car to stop. Therefore, I could say that the height of the ramp and the time it takes for the car to stop are directly proportional to each other.

  1. Bug Up Toy

    x Mass (kg) x Height (m), G.P.E. = MGH. As G is the constant value that represents the gradational pull of earth, M is Mass ad H is Height. If G always remains constant, then it explains G and H always multiplies and gives a constant value which means there is an inverse proportion.

    All the stacking blocks will be identical, ensuring that I always know by what amount I am increasing the height. Because of the need to use only one slope and bearing, and minimise accumulation of dust etc on the apparatus if I were to store them for later use, I will conduct my entire experiment in one lesson.

    This will be repeated 3 times for each height: 10cm, 15cm, 20cm, 25cm, 30cm. For the experiment, the same will be done, except the height will stay the same and the masses placed on the buggy will be: 100g, 200g, 300g, 400g and 500g.
