Conclusion
| Conclusion: |
Overall, i believe the inteded purpose of this experiment was to demonstrate how a force acts upon an object when the mentioned object has a varying mass. The multiple trials allowed us to experience the varying changes in velocity and momentum, and showed us that something as simple as adding a block to a cart could change the rate at which that cart travels. During the lab i felt as if these trials were tedious and repetitive, but towards the end i was able to observe the multiple sets of data we had collected and it did an excellent job at showing us how the mass of the object is able to change the object's impulse. One possible source of error we could have encountered, aside from possible weighing errors or equipment malfunctions, was the starting position of the cart and the rate at which we allowed the cart to accelerate. While this was mostly accounted for by including the individual velocity and position for each trial, it does not change that it makes the data more difficult to compare directly. Other possible sources of error could include: an unleveled track, a frayed or aged rubber band, a track that is not smooth, and a loosening knot on the string that connects to the cart. All of these error sources are minor and can be accounted for with proper preparation, but the original error i mentioned involving the starting position would take more strenuous testing.
