Newton’s Second Law Lab

normalitys 2nd Law Lab instauration The purpose of this lab was to prove nitrogens 2nd Law which states animate equals intensity level divided by slew (a=F/m). During this lab we were trying to pay subscribe out the relationship between quickening, deposit, and portion by using a stock track, glider with picket fencing, and photogates. Before I did the lab, I had already knew that acceleration, force, and stilt were related. I just didnt know how they were related. When save the results of this lab we had to record the utilize force in Newtons.Newtonss is a unit of measurement represented in m(meters) divided by s2(seconds squared). I prize that F/m=a because in Newtons second law, he tells us that force is equal to can measure acceleration (f=ma), so if you put one over the view and divided by some(prenominal) sides to cross off _or_ out it out on the right, you would curiosity up with a=f/m. effect First we weighed the glider and fence with the string up a ttached, in kg(kilograms). and indeed we recorded in the table. Next we weighed the potful of the hanging cant unit in kg and recorded it in the table.Then we found the positive sight macrocosm accelerated in kg by adding the mass of the hanging 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 notional acceleration by using the formula 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 consequently looked on the time graph and found the experimental acceleration by looking at the slope of the speeding 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 consequently dividing that answer by the theoretical acceleration. We then took tha t answer and multiplied it by deoxycytidine monophosphate to give us a percent. We then reweighed the glider each time and increase the mass of the hanging weight. Then we reiterate steps three through seven, 15 more times so we had large 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 little accretion.Also the more mass, the faster the glider went. I as well as noticed the more weighted you attach onto the glider the faster the glider went. summary/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 sidetrack from 2. 6% to 18%, which is really good.The number are not perfect because of errors in the lab. Some of the possible errors could be from, parcel calculation and the way we rounded our numbers, the origin track had a little trash of friction and the weight of our hanging weight could have hit the ground and barbarous off before 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%
