Spring Constant or force constant is defined as the applied force if the displacement in the spring is unity. It is denoted by k.
Consider a force F stretches the spring so that it displaces the equilibrium position by x.
The Spring Constant Formula
is given by
= Force applied, x
= displacement by the spring
Spring Constant formula is used to find the force applied, displacement and spring constant. It is expressed in Newton per meter (N/m).
