Air Resistance on a Fan Car :: science

transfer Resistance on a Fan Car job When a enlarged strike out is blowing air against the fan simple machine at three diverse speeds (high, medium, and low), then will the overall speed be lower?Materials Fan machine (KNEX pieces, small, battery-powered fan, wheels with tires) AA batteries Large 3-speed fan Timer Masking tape attend1. Load twain AA batteries into the fan that is attached to the KNEX car.2. sugar a starting line and a finish line two meters away from individually other with small pieces of masking tape.3. Plug in the large fan and place it approximately 5 centimeters away from the finish line.4. Place the fan car on the starting line with the small fan face up opposite the large fan.5. For the first test, test the amount of resistance when the large fan is off.6. move around the small fan on and time how long it takes for it to telescope the finish line with the timer.7. Repeat this test for three trails and record times and observations.8. For the second test, vomit up the large fan on a low context and time the fan cars progress.9. Repeat this test for three trails and record observations and results.10. On the third test, switch the large fan to the medium reach and time.11. Repeat the test three more times and record observations and times.12. For the last test, turn the fan on the highest setting and time the fan car.13. Record observations and work up all trails and times into a table and find the average time of each trail. ObservationsIn this particular lab there werent many things that I observed, though I will state the small amount that I did. I power saw that there was a slight incline on the scratch that we were testing the car on. I also observed that the wheel alignment kept fashioning the car veer off to the right. When the small and large fans were on I could hear their engines going. And when I turned the small fan off I base that it was very warm in my hands.HypothesisIf the fan car goes up against the win d provided by the large fan, then the car will go bumper-to-bumper with increasing resistance, because there is more opposition between the two with every increase of speed.Data/ResultsI organized my times, trails, and averages into a table and a represent to present my information.Results ChartSetting running 1 Trail 2 Trail 3 Average Time Distance SpeedAir Resistance on a Fan Car scienceAir Resistance on a Fan CarProblem When a large fan is blowing air against the fan car at three different speeds (high, medium, and low), then will the overall speed be lowered?Materials Fan car (KNEX pieces, small, battery-powered fan, wheels with tires) AA batteries Large 3-speed fan Timer Masking tapeProcess1.
