Question

FULL DEFINATION OF FORCE ITS UNIT ALSO and also dimensional formula

Answer 1

$\huge\underline{Force}$

Force is a push or pull which can change the position of an object .

Unit of force is Newton.

Its dimensional formula is

[M(1) L(1)T(-2)]

BE BRAINLY ☺

Answer 2

Spring Constant or force constant is defined as the applied force if the displacement in the spring is unity. It is denoted by k.

The dimensional formula can be worked out by using the spring force formula i.e. F = kx . This gives k = F/x. Dimensionally [k] = [F]/[x] = [M1L1T-2]/[MoL1To] =[M1LoT-2] .

its unit is:

  k units = Newton/meter = kg-m/sec^2//m = kg/sec^2 because the length unit (meter) cancels out.
