To investigate how the height of a ramp affects the speed of a trolley

The aim of the experiment was to investigate how the height of the ramp affected the time it took for the toy car to reach the bottom.

Equipment used

Ramp- I used the ramp for the trolley to go down

1-meter ruler- this was used to measure out the height of ramp and for when I was changing the height of the ramp for the investigation

Trolley- the trolley was used instead of a toy car because it weighed more than the toy car, and there is enough momentum.

Stop watch- This was used to measure the time in which it took the trolley and to run down the desired heights of the ramps

Clamp stand- a clamp stand was used to hold up the ramp

G clamp- this was used to hold down the ramp stand, because I needed the clamp to be steady.


The greater the height of the ramp the more the speed of the trolley
would increase.

I predicted that the more the ramp increases in height the more the

Pattern of graph

The pattern on the graph shows steady acceleration on the trolley at 
each chosen height. The graph also shows that the relationship between 
the ramps increasing in height the change in speed does increase as 
well. The graph also shows that the relationship between the height of 
the ramp and the change in speed is NOT directly proportional, but 
instead just proportional.

Length of ramp 9(cm)

Evaluation of my conclusion

I think that my experiment went well over all and was reliable as I repeated it 2 times to get an average, also I made sure everything was accurate and my graph showed this because as I accepted there was a positive trend which lead to a solid conclusion. There is an increasing GPE as the height increases and therefore led to an increase in kinetic energy and speed. The trolley is at is at its highest point of 60cm it has the highest GPE then as the trolley drops to a lower level it loses GPE. However it gains the same amount of kinetic energy. If the kinetic energy increases it means the speed is increasing because the mass of the trolley went hence taking less time to reach to the bottom of the ramp.

    easily, but anyway it can still provide a graph as I predicted. Evaluation In this experiment, my method was not very good. When measuring the height of the ramp, it was not very accurate, this would affect the result. To prevent this I should mark the height on the stand, this would me more accurate.

    I believe that the way I plan to carry out the experiment is good because there are not many scientific factors that could affect how the experiment changes as the variable does. In using the smart pulley system the results that I collect should be as precise and accurate as possible.

  2. Trolley Speed

    Newton law's of motion Every action has an equal but opposite reaction From this law we can explain the above diagram. In the above diagram Newton's law is present. Force 1 shows the ramp pushing the trolley forwards, and force 2 shows the trolley pushing back on the ramp.

    A light gate will be held up by the clamp and connected to the psion computer which will be placed at the base of the ramp. A card was attached to the toy car, the main reason for this was to provide the distance for the psion computer to calculate the speed.

  2. Investigating the Factors Which Affect the Motion of a Trolley Down an Inclined Plane

    Prediction: I predict that there will be no change in the speed that the trolley travels down the ramp at each different added mass variable. However, I feel that there will a be a degree of inaccuracy in the results because the ramp are not in perfect condition and they trolleys likewise are not frictionless.

    We must also look at the motion of the car in terms of energy. This will provide us with another way of finding the theoretical speed of the car at any stage, and will also tell us the total energy exerted during the car's movement down the ramp, and onto the floor.

  2. Investigation into factors affecting the speed of a car rolling down a ramp

    The mass of car can affect the force pushing the car and the distance travelled would affect the average speed. If I alter the mass of the car then I will not to be able to distinguish which factor between that and the height of the ramp are the cause of the change in the force behind the car.
