# Hooke Law - Force Needed

In short Hooke's law can be explained as " F = kx" and to explain it further Hooke’s law states that force need to compress or extend a spring is directly proportional to the distance covered and constant factor i.e. stiffness is considered during this calculation.

## Hooke Law

### To calculate Hooke Law:

• What you want to calculate

• Spring Force Constant(k)

N/m

• Distance from Equilibrium(x)

m

• Spring Equilibrium Position(x0)

m

• Force(Fx)

N

•

Formula:
Force:

Spring Force Constant:

Distance from Equilibrium:

Spring Equilibrium Position:

where,
Fx = Force,
k = Spring Force Constant,
x =Distance from Equilibrium,
x0 = Spring Equilibrium Position.
