... object) is directly proportional to the force acting on it. This law is only true if the elastic limit of the object has not been reached. * F- force acting on the spring * e- extension of a spring due to the force applied * k- spring constant The graph of force against extension can be plotted as shown below:- The shows a straight line through the origin up to a point where it starts to curve. This shows us that the spring stops obeying Hooke's law after passing it's elastic limit, after this point the spring is known to have undergone plastic deformation and therefore will not return to it's original shape. The gradient of the graph above determines the value on the spring constant 'k'. This value can be used in the equation of the simple harmonic motion for mass spring system as show below:- As we know that the mass ...
