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.

Hypothesis 

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

Prediction 
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.

Conclusion

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 will try to push the ball with the same force each time * I will use the same books to hold my ramp up each time to ensure that less errors are made * I will calculate the angle of the ramp so I can check that as the height increases so does the angle.

  2. How the height of a ramp affects the speed of a toy car.

    There will always be forces that could slightly affect the result, such as friction between the ramp and the cars wheels, and air resistance. There is no way I can control any of these factors, but they shouldn't affect the result too much.

    Friction results from the two surfaces being pressed together closely, causing intermolecular attractive forces between molecules of different surfaces. As such, friction depends upon the nature of the two surfaces and upon the degree to which they are pressed together. PLAN The experiment will be carried out as follows: 1.

    Ranges and amounts To make this investigation successful, we must choose a sensible range, and amount, of readings to record in order to come up with a useful and informative outcome. For example, in the primary experiment it would be pointless to experiment with heights ranging from 1cm-2cm because the speed difference would be minor.

    The bigger the gradient the more spaced out the dots will be because the trolley is travelling at a faster rate. The smaller the gradient the less spaced out the dots will be, indicating that the speed of the trolley is travelling at a slower rate.
