Is commonly known as “a pull or a push,” but scientifically, force does not stop there; it practically explains movements that occur around us. Since movement is change as a result of motion, and motion is the result of force.
Force is used to change the state of a body from rest to motion. Likewise, it can also change the motion of a body. Changes are controlled by forces.

The stretch in a spring is proportional to the force applied.
The proportionally between the F applied to the bottom hook of the spring and the displacement ∆x of thespring may be written with a proportionality sign:
F ∞ ∆x
Which is mathematically expressed as:
F = K∆x
where K is the proportionally constant of the spring known as spring constant.
