Question

Define force constant. Give its unit and dimensional formula.

Answer 1

constant force is defined as the applied force if the displacement in the spring is unity. It is denoted by k.
the dimensional formula is  (F = kx)

Answer 2

Spring constant or force constant is defined as the applied force if the displacement in the spring is unity. It is denoted as k.
formula is :
F=kx.
k=F/x
unit is:
Newton/ meter = kg/sec^2.
