Answer:
To the displacement from the equilibrium position
Explanation:
In a simple harmonic motion, there is a force acting on the object in motion, and this force is given by
[tex]F=-kx[/tex]
where
k is the elastic constant
x is the displacement of the object with respect to the equilibrium position of the system
The negative sign means that the force is a restoring force: it tends to bring the object back to the equilibrium position.
We see, therefore, that the force in a simple harmonic motion is proportional to the displacement (x) of the system: the larger the displacement from the equilibrium position, the greater the force that tries to bring it back to equilibrium.
