What are the units for the spring constant, k? newton meters newton seconds newtons/meter newtons/second newtons/seconds2

The SI unit of spring constant is Newtons/meter (N/m).

Explanation:

The force acting on the spring is given by Hooke's law as :

Where

k is the spring constant

x s the compression or stretching in the spring

Negative sign shows that the force is acting in opposite direction of compression and stretching.

The SI unit of force is newton and the SI unit of distance is meters. So, the SI unit of spring constant is Newtons/meter. Hence, this is the required solution.
