Proving newtons second law

Question: what is the relationship between Force, Mass, and acceleration ?

Materials Used: Car, Weights, Scale.

Hypothesis: They are all elements of an object. They all affect each other in an experiment.

Procedure: Step one: we started off with setting up the board flat. we put the 200g weight and pulled the car with the scale. We put down the results we got.

Step two: We then inclined the board and pulled the car up with three different weights. 20,100,200. WE wrote down the results and we also had the board inclined on the text book.

Step three: we then changed the incline again and put it up on a weighing scale. We changed the weights so we could get different results.

Step four: when we were done finishing that we had our graph all filled out.

Step Five: We then made a line graph and we had finished



Graph:


Height /  flat /  textbook /  scale / acceleration
200g    200N   .6            110           1
20g      .1N      .2            50           10
100g    .5N      .25          70            10



Conclusion: Our conclusion ended up being weird because our graph and measurements didn't make any since so we had to keep trying to correct it but it didn't come together. However i had fun doing the experiment and i am looking forward to having our next lab.
