Hooke’s Law States That The Force, F, In A Spring Extended By A Length X Is Given By F = −kx. According To Newton’s Second Law F = Ma, Where M Is The Mass And A Is The Acceleration. Calculate The Dimension Of The Spring Constant K?

Answer»

Given, F = -KX

⇒ k = – F/x

F = ma,

the DIMENSIONS of force is:

[F] = ma = [M1L0T0].[M0L1T-2] = [M1L1T-2]

Therefore, DIMENSION of spring CONSTANT (k) is:

[k] = [F]/[x] = [M1L1T-2].[M0L-1T0] = [M1L0T-2] or [MT-2] …..

Given, F = -kx

⇒ k = – F/x

F = ma,

the dimensions of force is:

[F] = ma = [M1L0T0].[M0L1T-2] = [M1L1T-2]

Therefore, dimension of spring constant (k) is:

[k] = [F]/[x] = [M1L1T-2].[M0L-1T0] = [M1L0T-2] or [MT-2] …..
