Displacement of the spring (given force and constant)
Formula
x
the displacement of the spring\'s end from its equilibrium position
k
the rate or spring constant
Formula description
In mechanics, and physics, Hooke\'s law of elasticity is an approximation that states that the extension of a spring is in direct proportion with the load applied to it. Many materials obey this law as long as the load does not exceed the material\'s elastic limit. F in direct opposition to the direction of x.
