I. Introduction:
The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration, force, and percent error one will be able to distinguish and evaluate the relationship between the two laws. II. Procedures of experiment:

All groups had to complete two types of labs. The first lab our group had to complete was completed like so: using a car one had to tie a piece of string approximately 80 centimeters in length to a toy car on a ramp. This string was then feed one top of a super frictionless wheel. The end of the rope that had the end nearest to the ground was tied off with a 0.2kilogram weight. The car was then pulled back by a participant until it reached 0.8 meters and was let go. A second participant would then record the time it took for the car to reach the end of the ramp. This was repeated a few times. One would add 0.5 kilogram weight to the car and the time was then recorded in a similar fashion. These times would be recorded into a table and would be used as raw data. The second part of the lab was different in that: a group had to tie a small scale to opposite end of the rope where the weight was located. Immediately following that scale, one would then tie a toy car. After the toy car another scale would be attached; likewise another car would follow. One student would then pull the whole system back before the back end of the second car would touch the wall provided by the ramp. Immediately after that student would release the system he and a second student would read the scales. Essentially, one student would have to read one...
