Past Research

Today I searched my question on the internet to see peoples thoughts/ results on this experiment and i found this one specific site , This experiment did something similar to my experiment but it used weights and springs to find the results instead of what i did with the elastic band and the newton spring scale. This site also talks about a scientist in 1676 named Robert Hooke who performed this sort of experiment and received the same sorts of results that I received. Hooke realized that the more force that is put on to a piece of elastic or a spring, the more it will stretch, and he also realized that the length increased by the same amount every time the force was increased by a fixed amount.

Graphed Results

Here I took the measurements I found in my table and put them into a graph, and it turned out looking like this:


 Here are the results I found when i performed this experiment:
Force Used (newtons)
Length of Elastic Band
8 cm
16 cm
24 cm
32 cm
40 cm
48 cm

Note: If you are planning to do this experiment, remember your results will not be the same as mine because of the chance of the elastic band being different in length, thickness, etc. 

Items used

For this experiment, i used the following tools:
Newton Spring Scale
Elastic band
Graph Paper

I got my results in this experiment by doing the following:
1. Find the original length of the elastic band by putting it across the ruler.
2. Pull the elastic band and check the length of the elastic band with your ruler every 2 newtons (which is measured by the newton spring scale).
3. Put results down in a well made table showing the amount of newtons used, and the length of the elastic band.
4. With this table, put the information into a graph.
