I am going to investigate the different factors that affect the velocity of a trolley going down a ramp.


What is velocity?

Velocity is how far an object has travelled, compared to how long it takes.

How is it measured?

I will be putting ticker tape on to the trolley.

When the trolley has gone down the ramp I will count the last 10 dots and dividing that by the time which is 0.2 sec and that will equal the velocity.



I will have only one variable element which will be the height of the ramp as this is what we are investigating.              The components which we will keep consistent throughout are:-
  Mass of the Trolley -As the force which will be acting on the ramp must stay the same throughout, and the mass is what will determine this. To control this quandary we will use the same trolley each time.
  Friction will slow down the speed at which the trolley travels. A

Diagram to show how I will set up the apparatus:

Once I have set up my apparatus like so, I will switch the ticker timer on and release the trolley so that it can accelerate down the ramp. I will measure its velocity from the very point it leaves the ramp for 1m. I chose 1m as it is a suitable distance, if I was to have a number any smaller the trolley may not have yet reached its average speed.
I will carry out the investigation, by doing each height 3 times to ensure accuracy in the results.


There are no real safety issues to worry about, however to be certain that there

In conclusion to the investigation, I believe that the experiment went very well, I did not overcome any major difficulties, and feel that I achieved the best of my abilities. However given more time and better apparatus to measure the velocity of the trolley I think it could have been more accurate. Possibly a centisecond timer or millisecond timer which have the sensitivities to be able to measure the velocity of the trolley up to 1/1000s would have guaranteed better accuracy. Nevertheless I am pleased with the experiment.                                                                                    Taking 3 sets of results on each height proved the ticker timer to be dependable as both the readings were practically the same each time. By taking 3 sets of results also ensured myself that I should not get any weird results, which I didn't, I know this as the line of best fit went through my plotted results on my graph.                 Given more time I would have repeated the whole experiment and maybe taken 5 or more readings of each height to guarantee that my results were reliable. Furthermore, I am still sure that my results are of a high degree of accuracy and are dependable enough to draw a reliable conclusion.

    As you can see, it is now a common sense that as the number of springs gets higher, the lower the frequency (number of oscillation in a given time), and as the number of springs gets fewer, the higher the frequency.

    Also at the bottom of the ramp some sort of barrier will need to be placed to prevent damage to the trolley as it hurtles off the edge, or to thwart potential harm to any unsuspecting pedestrian/small animal. That's basically it, the rest is all common sense.

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

    There is no particular amount it decreases by each time because of slightly inaccurate results but is still decreasing. This is reflected in my velocity height graph where between 20 and 25cm heights the difference in velocity is very large and it gradually gets smaller as the height gets bigger bringing the graph round in a curve.

    Also, another thing, which will help us to get accurate results, is our choice of apparatus. To measure the stopping distance of the trolley more accurately, we are going to measure the braking distance from the end of the runway to the back wheels of the trolley using a 1m ruler.
