Materials
Young's Modulus
Ratio of stress and strain of a material, up to limit of proportionality
Pascals - \(Pa\)
Stress
Ratio of force exerted to the area across which it is applied
Pascals - \(1\,Pa=1\,Nm^{2}\)

Hooke's Law
The ratio of the force exerted on an elastic material to the extension of the material, up to the limit of proportionality.
Newtons per Metre - \(N\,m^{-1}\)
-
Limit of Proportionality
The maximum extension for which extension in directly proportional to the load on the material
-
-
- Springs in series add spring constant
- Springs in parallel add inverses of spring constants and take inverse
-
Density
Mass per unit volume
\(kg\,m^{-3}\)
-
Elastic Strain Energy
The energy stored in an elastic material, that is released when the material returns to it's original shape
