Determine the equation of the relationship between the force and the extension. Hooke's Equation: Fs = -k(delta)x
Let , A block is attached to a spring having spring constant .A force " "is applied and spring has got an elongation of units .
now,
Hooke's Law states that the force needed to extend or compress a spring by some distance is proportional to that distance or we can say that ,that restoring force is equal to the negative of the displacement (deformation) times a constant.
Mathematical representation of HOOK'S law is :
where:
There is a negative sign on the right hand side of the equation because the restoring force always acts in the opposite direction of the displacement (for example, when a spring is stretched to the left, it pulls back to the right).
