## Question:

Which law should be used to solve the question below:

A load of 45 N attached to a spring that is hanging vertically stretches the string 0.14 m.

What is the spring constant?

## Spring Constant of a Spring

Springs are some kind of mechanical objects that can be deformed or stretched under the action of force and these objects retain their original shape on the removal of the applied force. A metal wire wound like a long coil makes a spring. Spring constant is a characteristic property of each spring and it is expressed in terms of Newtons per meter.

• Spring constant of a spring or the stiffness constant of a spring is the force required to stretch or compress a spring by unit distance.
• If F is the force required to stretch a spring by x meters, the spring constant can be expressed as {eq}k = \dfrac { F } { x } {/eq}
