Newton’s Second Law Lab

nitrogens 2nd honor Lab origin The purpose of this science lab was to prove Newtons 2nd Law which states accelerate extend tos force separate by gage (a=F/m). During this lab we were trying to find verboten the relationship between quickening, force, and spate by using a channelize track, sailplane with picket fence, and photogates. Before I did the lab, I had already knew that acceleration, force, and pack were related. I just didnt whap how they were related. When recording the progenys of this lab we had to record the use force in Newtons.Newtonss is a unit of measurement represented in m(meters) separate by s2(seconds squared). I think that F/m=a because in Newtons second law, he tells us that force is fitted to mass ages acceleration (f=ma), so if you take the mass and divided by both sides to cancel it out on the right, you would end up with a=f/m. Procedure First we weighed the sailplane and fence with the cosmic string attached, in kg(kilograms). Then we rec orded in the table. Next we weighed the mass of the suspension system weight in kg and recorded it in the table.Then we nominate the broad(a) mass being accelerated in kg by adding the mass of the temporary removal glider to the mass of the hanging weight. Fourth we found the applied force by taking the mass of the hanging weight and multiplying it by 9. 8(gravity). Then we found the theoretical acceleration by using the command a=F/m and plugged in the total mass for m and the applied force for F. By taking F and dividing it by m we can up with the theoretical acceleration. We whence looked on the time graph and found the experimental acceleration by looking at the slope of the velocity time graph and recorded it on the table.Lastly we found the percent difference by taking experimental acceleration, subtracting it from the theoretical acceleration, and then dividing that answer by the theoretical acceleration. We then took that answer and multiplied it by 100 to give us a pe rcent. We then reweighed the glider to each one time and increased the mass of the hanging weight. Then we repeated move three through seven, 15 more times so we had decorous data. Results/Observations Result are on the attacked sheet. Durning the lab, I observed that the more mass that was on the hanging weight the less accretion.Also the more mass, the faster the glider went. I also noticed the more weighted you taped onto the glider the faster the glider went. Analysis/Conclusion I think a=f/m because in Newtons second law, he tells us that force is equal to mass times acceleration (f=ma), so if you take the mass and divided by both sides to cancel it out on the right, you would end up with a=f/m. After this lab, we turn out that this theory is right because when you look at the theoretical and experimental acceleration data and you look at the percent difference, they vary from 2. 6% to 18%, which is really good.The numbers are not perfect because of errors in the lab. roug h of the possible errors could be from, software calculation and the way we rounded our numbers, the air track had a little bit of friction and the weight of our hanging weight could have hit the ground and fell off in the first place the picket fence went threw the the photogate. In conclusion, our lab proved that acceleration does equal force divided mass because when we took the applied force and divided it by the total mass and come up with the theoretical acceleration, our data result came back with an average percent difference is 5. 04 which is less then 10%
