The force constant, also known as the spring constant, quantifies the stiffness of a spring in Hooke's Law. It is denoted by $k$ and measured in Newtons per meter (N/m).

We could also define force to mean that a moving object with no force acting on it continues to move with constant velocity in a straight line. If we then observe an object not moving in a straight line with a constant velocity, we might say that there is a force on it.
The force constant, often denoted as $k$, is a measure of the stiffness of a spring. It is defined in Hooke's Law, where the restoring force $F$ is proportional to the displacement $x$ from the equilibrium position: $F = -kx$.
What we have been calling “pushes and pulls” or “external influences” is called force in physics. Most people have an intuitive idea of what force is, and like so many other physics concepts, this intuition is likely wrong. We'll start by saying what force is not, then move on to its definition.
Definition. A measure of how stiff or resistant a spring is; also known as spring constant.
An intuitive definition of force —that is, a push or a pull—is a good place to start. We know that a push or a pull has both magnitude and direction (therefore, it is a vector quantity), so we can define force as the push or pull on an object with a specific magnitude and direction.
10 maj 2023 · Force constant is the amount of force that causes a unit extension. It is the ratio of force to extension of an elastic material. K → force constant, stiffness or elastic constant.
