Answer:
x is the displacement of spring
Explanation:
The Hooke's law gives the force acting on the spring when it is compressed or stretched. The mathematical expression for force is given by :
[tex]F=-kx[/tex]
Where
k is the spring constant of and it shows the stiffness of spring.
x shows the displacement of spring when it is stretched or compressed from equilibrium position and it acts in opposite direction.
