stiffness property
final
The spring constant (k).
The units of stiffness are M/T², where M is the mass unit used for the value of the mass property, and T is the time unit used for driving the SpringSimulation.
Stiffness defines the spring constant, which measures the strength of the spring. A stiff spring applies more force to the object that is attached for some deviation from the rest position.
