Find how extension changes with different weights
Linear relationship
Eliminates parallax errors
Extension=new length−original length\text{Extension} = \text{new length} - \text{original length}Extension=new length−original length
Always wear eye protection
Read measurements at eye level
A force, measured in Newtons (N)
No, measured in grams (g) or kilograms (kg)
Approximately 1N
Force (weight) in N
Extension in cm or mm
Straight line through origin
Point beyond which extension is no longer proportional to force
F=kxF = kxF=kx (F=force, k=spring constant, x=extension)
k=Fxk = \frac{F}{x}k=xF = gradient of graph
