  1. ECUATIILE OSCILATORULUI LINIAR ARMONIC

  2. Fie resort elastic care are lungimea l0 in stare nedeformata. • Conform legii lui Hooke deformarea unui resort elastic este proportionala cu forta care actioneaza asupra resortului. • Forta elastica care ia nastere in resort este deasemenea proportionala cu deformarea resortului dar de sens opus • Fe=-ky • Unde y estedeformarearesortului
