Hooke's Law
From ProofWiki
Physical Law
Hooke's Law applies to an ideal spring:
- $\mathbf F = -k \mathbf x$
where:
- $\mathbf F$ is the force caused by a displacement $\mathbf x$;
- $k$ is the spring force constant.
The negative sign indicates that the force pulls in the opposite direction to that of the displacement imposed.
From dimensional analysis, the dimension of $k$ is $MT^{-2}$.
