An Investigation To Find Out What Affects The Stopping Distance Of A Toy Car


We are going to investigate how changing the height of the starting position of the car of the ramp affects the stopping distance of the toy car.


Things we could change to affect the stopping distance –

  • Gradient of ramp
  • Speed
  • Counter forces
  • Mass of car
  • Starting position of car on ramp

Dependant Variable:

We will investigate a change in the starting position of the car on the ramp.


  • A ramp
  • A toy car
  • 3 or 4 metre rulers (depending on the distance the car travels)
  • Clamp stand (to support the ramp)

Fair Test:

        To make our test fair there are several things that we will have to keep the same:

  • The same toy car must be used each time
  • The ramp must stay at the same height
  • The same ramp must be used
  • The distance must be measured in the same units (e.g. cm)

  • Set up the apparatus as it is show in the diagram
  • Make sure the ramp is marked at every 10cm from the bottom of the ramp
  • Start the toy car from behind the 10cm mark on the ramp, let it roll down the ramp and measure the distance it travels with the rulers. If it doesn’t travel in a straight line (or fairly straight direction) do this again.
  • Repeat this twice so you have three different results
  • Do the same thing every 10cm up the ramp until 90cm three times each
  • Find an average result for each height by using the 3 different results for each height.


I predict that the further upwards the car is started on the ramp, the further it will travel which means the stopping distance will be longer. This is because when the car is high up on the ramp it has a longer distance to accelerate.

        Except for the obvious way the distance travelled becomes higher the higher the stopping distance was, there aren’t really any other patterns in our results. For the first few results (10, 20, 30, 40) I noticed a small pattern which doesn’t really continue further on. When you look at one result for a height, then a different one from that height doubled (eg. Look at the average from 10cm then from 20cm), the average is almost doubled. This only works for a couple of the results but perhaps if we had gotten more accurate results this would have been clearer and shown another pattern.

  1. Rolling a Car down a ramp.

    EVALUATION The experiment worked well after my preliminary experiment where I learned that my heights from were too high so I wouldn't get very good results. Once I had done that my results were accurate and the method worked. Due to human error and reaction time, these results could not

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

    I know that the height affects the speed, this is because the higher the car is the more gravitational potential energy it will have and since the air resistance and friction will have no effect all the gravitational potential energy will be converted to kinetic energy, making the car travel faster.

  1. Investigation is to see how changing the height of a ramp affects the stopping ...

    the graph which has been drawn, it has given me useful information. My graph basically shows me that as I increase the height of the ramp, the stopping distance for the car also increases. You are clearly able to see that my graph has produced two anomalous results as they

  2. Investigating the relationship between the speed of a model car and its stopping distance.

    My simple results table would, therefore look something like this: (Remember 1 block is 1 cm high) Height Speed Distance 1 Block 0.52m/s 25 cm 1 Block 0.49 m/s 24 cm 1 Block 0.51 m/s 23 cm Average 0.51 m/s 24 cm 2 Blocks 0.68 m/s 41 cm 2 Blocks

  1. Investigating The Stopping Distance Of A Toy Car

    E.g if the velocity of the car is 10m/s then using our previous formula we can see that D= m 10 = D= m X 100 2F 2f If doubled we can see that 20 = 400 From this we can see that if speed is doubled the stopping distance will increases by a factor of 4.

  2. Squash Ball and Temperature Investigation

    Basically if the equipment could have been more advanced such as the electronic water bath, lasers to measure heights, machines to drop the ball with the same force, electronic thermometers that read off values accurately etc, the results would have been far more accurate and the chance of producing anomalous results decreased substantially.

  1. Approximate Stopping Distances

    For example it is the time required to detect that a pedestrian is walking across the road directly ahead and to decide to apply the brakes. Movement Time: Once a response is selected the driver must perform the required muscle movement, for example the time it takes to lift the foot off the accelerator pedal and press the brake pedal.

  2. In this experiment I aim to find out how the force and mass affect ...

    That�s basically it, the rest is all common sense. Fair Testing As with all scientific experiments, only one variable must be altered at one time. All the rest must remain constant to ensure good sensible results. By using present knowledge, I know that the following factors can affect the outcome and must be controlled: ? Height of ramp -
