Investigation of the speed of a trolley down a ramp and its gradient

        In this investigation I will be testing how the speed of the trolley is affected by the gradient of the ramp. The speed of the trolley will be affected by the gradient of the ramp by many factors. One of these factors is gravitational potential energy. GPE is the energy stored in an object because of its height. The energy is stored as a result of the gravitational pull of the earth for the object. GPE is also affected by the mass of the object but I am going to use the same trolley. I am going to increase the gradient of the ramp and therefore increase the height of the trolley. The higher the trolley is on the ramp, the more GPE it should have and this energy will be transferred to kinetic energy when the trolley is released from the top.

Gravitational potential energy = mass x gravitational field strength x height moved

        The trolley moves so it has gained kinetic energy.

Predictions: Based on the preliminary work I predict that the acceleration of the trolley will increase when the gradient of the ramp is increased.

Risks: There aren’t any major risks in carrying out this experiment but a few precautions need to be taken such as making sure that there is no one near the end

The results show that my prediction was right and that the acceleration of the trolley down a ramp increases as the height of the ramp is increased.


The experiment was done quite well and the results gathered were accurate and repeatable. The accuracy of the acceleration should be very accurate as it was done by a computer but the height of the ramp was measured and set up by me so the accuracy of the heights may be a little varied as it was done by a human but the results are still very accurate. I did not have any anomalous results probably because the trolley was rolled down the ramp from exactly the same point and the computer didn’t make any errors. The experiment could have been improved by using more accurate measuring instruments and reducing the chance of human error. The experiment could have been extended if I carried out more runs for one height to find a more accurate average and also I could have tested more heights to see if the trend is the same.

  1. What affects the acceleration of a trolley down a ramp?

    The trolley fell too rapidly and I found it hard to time with a stopwatch. Therefore in my final investigation I shall have the shortest height as 20cm and the tallest height as 45cm. I shall measure every 5cm in between because 5cm make a considerable difference in the speed.

  2. Investigate and measure the speed of a ball rolling down a ramp.

    And when the G.P.E increases this means that when the object is moving downwards the kinetic energy also increases, because there would be more speed when rolling down. And that graph and results fully support my prediction number two, which states that when Gravitational potential energy increases the Kinetic energy also increases proportionally.

  1. An investigation into the acceleration of a trolley up a ramp.

    Why do you think that these are important? I can only change one of these if the experiment is going to be a fair test. Any other changes, even a minute one will result with the reliability of the results being jeopardised.

  2. An investigation into factors that effect the braking distance of a trolley

    Both potential energy (mgh) and kinetic energy (1/2mv2) are affected by height of the trolley, if it is increased then so are the potential energy and the kinetic energy. This means that if the kinetic energy is greater, then an equal breaking force being applied in each case will take

  1. Trolley Speed

    Conduct the experiment in a sensible manner. Results/Conclusion My results show that as you increase the height of the ramp you also increase the speed therefore decreasing the time taken for the trolley to travel down the ramp. Looking at my graphs I can see that they all support my hypothesis and all backup my predictions.
