Hooke's Law Calculator

If you want to determine the value of force in any spring that can expand or contract, then you can use Hooke's law calculator.

In physics, Hooke's law states that the stress/force on a flexible but solid substance is directly proportional to the produced strain/opposite force,


from the substance's elastic limit, stress is always less. It means that the displacement and force are directly proportional to each other. As the force on the spring increases, it increases the displacement as well. A push or pull applied on an object with mass that causes the body to change its velocity is known as force. You can find more about the force in our force calculator.


Formula of Hooke's Law Calculator

By using the equation listed below, you can easily find the force in an elastic object. Or, if you want to determine it instantly, you can jump to our calculator.

F = -kΔx


F = spring force

k = spring constant

Δx = displacement


To check Gauss's law, you can use our Gauss's Law Calculator.


For a more precise understanding of concepts, let us have an example below:

Suppose a spring is stressed by the displacement of 0.15 m, whereas the spring constant applied on it is 80 N/m.Find the value of force exerted on a spring.

Given data

Spring Constant= 80 N/m
Displacement = 0.15m

To Find

Force exerted on a spring = ?


By using the formula listed below, you can find the value of force applied to the spring.

F = -kΔx

Putting values in the formula:

F = -80 * 0.15
F = 12 N
