MATERIALS

  • 2 Arbor Scientific Pull-Back Cars
  • Timer
  • Measurment Device (Meters)
  • Paper and pencil to graph results

OUR PROCEDURE

To carry out the procedure we used two pull-back cars. We measured the distance that they were pulled back, and then how far and long they traveled.  We conducted three trials for each distance, and then found the average.

CONCLUSIONS

The distance that an individual pull-back car travels after being pulled back a specific distance is consistent.

The amount of time an individual pull-back car travels after being pulled back a specific distance is fairly consistent. At 1.2m, the time that the car travels is at its peak. When the car is pulled back less than that, it will not travel as far as it could. Likewise, a car that has been pulled back too far will not travel as far either.

For the most part, an individual pull-back car will not travel in a straight line. On occasion, the path of the car will remain straight.

Not all pull-back cars behave similarly. We tested two cars which produced very different results. One car was able to travel in a straight path for a longer amount of time. The other car rarely traveled in a straight line and never traveled for a long time.

CONCLUSION

We would recommend the use of these cars. They were able to travel a reasonable distance before stopping, and were able to travel in a straight line. Not only that, they provide entertainment and can be used for scientific purposes.
