Introduction

GCSE Physics - Force,Mass and Acceleration Coursework

Method

        In this experiment I aim to find out how the force and mass affect acceleration. I shall do this by setting up an experiment involving a ticker tape timer and trolley, to keep the experiment as fair as possible I will only change one variable at a time. For the first part I will only vary the force (see fig. 1) in difference weights of 1N, 2N, 3N and 4N. In order to keep the friction acting on the trolley constant I will make the ramp which the trolley is on at the exact angle so it would keep moving at constant speed if I pushed it, this simulates no friction. Also I will keep the mass of the trolley constant by weighing it on a top pan balance. Finally the ticker timer was kept at constant time intervals.

        Aswell as varying the force I decided to vary the mass of the trolley in masses of an extra; 100g, 200g, 300g and 400g. However as in the first part I have to keep the other variables constant,

Equipment: I will need a special ramp with elastic at one end, books to put under the ramp to get elevation, but the elevation must be so that it is a friction/gravity compensated. A trolley, a ticker timer and tape. String to tie the falling weights to the trolley. Weights with 100g masses on, and also masses of 1kg for the trolley.

Fair test: Making sure that the tests are fair is quite a major factor in our experiment, because we have to keep all the experiments the same i.e the method in which we do it has to keep the same.

Predictions: I predict that the more kilograms that are put on the trolley, the slower the trolley will go down the ramp.

Procedure: When the equipment is set out as above then we will tread some ticker tape through the ticker timer and Cellotape the end to the trolley. I will put the trolley at its starting position (at the start of the ramp) and then when I am ready I will start the ticker timer and start the trolley down the ramp, and when it reaches the end I will stop the ticker timer.

Conclusion

My prediction was completely correct because I said that the more weight that was put on the slower the trolley would go, and I have enough evidence to confirm that my prediction was correct.

Analysing evidence and conclusion

        We can conclude that the more weights that are put on the slower the trolley goes down the ramp. The reason for this statement to be true is because the more weight that is put on the trolley the more downwards force is exerted on the trolley, and the force is greater than gravity and so it goes slower down the ramp than it would do if I had no weights on it. It also causes more friction between the ramp and the wheels of the trolley and so therefore goes even slower down the ramp. My results compare very well with my predictions because I said that the more weights that were put on the trolley the slower it would go and as my results showed I was correct.

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

    Set up the equipment as shown above. The ramp should be held up by the clamps and at a height of 35cm. 2. Measure a distance of 1m from the back of the ramp and mark. 3. Place the trolley at the back of the ramp. Hold in place.

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

    Obviously what was occurring in the experiment was as more and more mass was being added to the pulley, the gravitational potential energy increased. This in turn led to kinetic energy because the mass was falling, pulling with it the trolley.

  1. To determine the relationship between mass and acceleration when force is kept constant.

    But if we look closely only one of them is with 4 decimal points and the majority is with 3 decimal points, therefore I come up that the uncertainties for average acceleration is ?0.0005. Summary of all the Error Uncertainties Mass of cart (kg)

    This means that the distance between the averages will be larger because the car is travelling further. The graph shows us that the height up the ramp is directly proportional to the distance travelled, but there are some outlier averages on the graph at average points twelve centimetres up the

    At 0g to 50g there was no extension and from above 50g to 250g the elastic extended slightly, but in a non linear manner. This is explainable as for different materials of elastic, certain masses would have little or no effect on the extension, and the elastic would only extend at a constant rate for certain mass and onwards.

    Principle of Conservation of Energy - energy can never e created or destroyed: only converted from on to another. Energy is only useful when you transfer it from one form to another. When something falls, the potential energy is converted to kinetic energy: Kinetic Energy gained = Potential energy lost Power is the rate of doing work.
