Answer:
The force applied to a spring equals the product of the spring constant and the displacement.
Explanation:
From Hooke's law, the force required to extend or compress a spring by a distance is proportional to the distance. This means extension is proportional to force.
Mathematically it is stated as;
F= -k*x  where k is the spring constant and x is the displacement of the spring after adjustment.
Hooke's law is an example of elasticity property of a material which is the ability of the object to return to a normal shape after experiencing a distortion also called "restoring force"
