... us result because all the others are above 530 but this result is below 500. This is an error. To ensure accuracy through out the experiment I repeated any results when the car hit the ruler or the light gate. When we increased the speed to a certain amount the car gradually curved towards the ruler, which it eventually hit. Due to this fact I had to ensure the car was let go of straight down the ramp and not at any slight angle. This was very hard to keep constant because the angle of the car looked straight enough to the eye but was probably out. Also to ensure accuracy we had to make sure we looked down as close to a 90-degree angle as possible when measuring stopping distances off the ruler, this might of caused error in the results. We also used a separate ruler to measure across from the front of the car to the meter ruler, this was also hard to keep at a right angle to the car because the bonnet of the car was curved. Sometimes I accidentally pushed the car when carrying out this operation and therefore repeated that measurement. Also we had to ensure that the light gate was positioned correctly. The car had to pass through on the flat ...
