10 cards from this deck
Material storing elastic PE, returns to original shape when released
Max stress/deformation without causing permanent deformation
Force is directly proportional to extension/compression
F=kxF = kxF=kx
N m−1^{-1}−1 (newtons per metre)
Stiffer spring; more force needed for same extension
Es=12kx2E_s = \frac{1}{2}kx^2Es=21kx2
At equilibrium position
kx=mgkx = mgkx=mg (spring force balances weight)
Elastic PE max, kinetic energy zero
