Aim: The aim of this experiment is to test if the rougher surfaces produce more friction and affects the distance travelled of a toy car.
The aim of this experiment is to determine if the surface areas affect the distance travelled of a toy car by creating friction between the surface and object.
The aim of this experiment is to determine if the surface areas affect the distance of a toy car due to the force of friction between the two objects.
Hypothesis:
From the basic research shown, there is enough information to back up that the rougher surfaces will produce more friction, which would result in causing the car distance to be minimized. The surfaces such as the carpet and cardboard will produce more friction and affect the …show more content…
distance the car travels. The independent variables are the surfaces of the ramp and the dependent variable is the distance the car travels. The toy car, angle of the ramp, force applied to the car and where the car is released are all controlled variables because they will constantly stay the same. There will be the scientific principle proven that the surfaces can affect the distance objects travel due to the strength of the force of the friction created. In the experiment it will be proven that an energy transformation will be present when the energy changes from Gravitational Potential Energy to Kinetic Energy. The experiment will determine if the surface area affects the distance a toy car travels due to the force of friction.
I make a strongly educated guess from the basic research I’ve done that, the surfaces that are fairly rough, will produce more friction which means the toy car won’t travel as far. I believe that the surfaces such as the carpet and the cardboard square will produce more friction so therefore the car won’t travel as far. The independent variables are the surfaces of the ramp and the dependent variable is the distance the car travels. The toy car, angle of the ramp, force applied to the car and where the car is released are all controlled variables because they will constantly stay the same. The experiment will determine if the rougher surfaces produce more friction and affects the distance travelled of a toy car.
Discussion:
From the results shown, the hypothesis was proven to be correct in stating that the carpet and the cardboard produced the most friction out of all 7 materials and made the car travel the least distance.
My hypothesis was supported by the results from the testing of the different types of ramp surfaces and a toy car. The furthest results were recorded when the plywood smooth square was the ramp for the toy car. This means that there was less friction created which let the toy car travel further. There was an obvious difference in the results that were taken between the plywood smooth surface and the carpet, which produced the most friction. When the car was released on the carpet ramp, there was a lot of friction created between the car and the carpet. The friction made between the car and the surface made it travel not as far as say the mirror because there wasn't as much friction created. All of the results depended on the different surfaces of the ramp and how far the car travelled. In each test throughout the experiment, several trends could be seen within the data. For each different measurement there were 6 trials done. Trends were seen in each different test for each surface which mostly supported the scientific principle explaining that the surfaces of an area affects the distance an object travels due to the strength of the force of friction created between the surface and the
object.
Different trends were seen throughout the experiment. Trends were seen when testing the carpet square, where the results basically were constant staying around 1.70m – 2m with no major jumps between the trial results. This trend was also visible in the testing of the plywood smooth surface. Except in this test the results were constant up until trial 5 and 6 when the results started to drop. This must have been because of mishap during the trials; because of the edge of the surface area between the floor. Where as for the other surfaces, the results did vary in distances. These trends were seen in the graph and results table. The experiment also proved that there was an energy transformation from GPE (gravitational potential energy) and kinetic energy. This happened when the car was about to be let go of at the top of the ramp (GPE) to when it was let go and traveling down the ramp (kinetic). In each surface area test measurements, mostly the same trends could be seen. The surface area of the ramp was proven to make a difference in the experiment.
When the ramp surface area was rougher, there was more friction created which made the distance the car travelled decrease. When the surface area was smoother the further the toy car travelled. In the experiment, there were certain variables that needed to be controlled so it would be a far test.
