Purpose:
The Hooke's Law lab's objective was determine how much force (n) it takes to fully descend a spring to its maximum distance.
The Hooke's Law lab's objective was determine how much force (n) it takes to fully descend a spring to its maximum distance.
Theory:
To determine the Newtons from grams is to take the amount of grams and multiplying it by force of gravity which is 9.8g and then dividing it by a thousand to determine the unit conversion for Newtons.
F=-Kx equation used to calculate force
F=9(g)*9.8(G) example used to calculate
F=0.0882 solution that is produced (refer to data table)

Experimental Technique:
To conduct this experiment, I used brass weights measured in grams , a small spring, a stand with a pole for the spring to hang off of it, a mirrored measuring platformed in centimeters and a lightweight grams holder to hold the weights in place.

Analysis:
F=KX
F=6(grams)*gravity(9.8)/1000
K=.0588/2.5cm=.02352 n/cm
F=KX
F=6(grams)*gravity(9.8)/1000
K=.0588/2.5cm=.02352 n/cm
Conclusion:
The overall problem was how much weight in grams does it take to distend a spring to a specific level. After I set up the station with the stand and weight holder, I recorded the data onto a spreadsheet which included the mass in grams and the position in centimeters. I then had to convert to Newtons using a specific equation. After the force in Newtons was discovered, it was then possible to examine how much force was produced after the weight in grams was added. In order to evade parallax error from recording the wrong position in centimeters, the ruler had a mirror to properly line up from eye level to the top of the weight holder or the very bottom of the spring. The spring was very close to the ruler instead of on the hook to avoid error as well. Once it was completed, a graph was built. After thoroughly examining the graph, it proved an understanding of how much force was used to distend a spring to a specific level.
