Oscillation Side by SideEdit

When apply a force on an object of mass attach to a spring . The spring will move a distance y above and below the equilibrium point and this movement keeps on repeating itself for a period of time . The movement up and down of spring for a period of time is called Oscillation


The force acts on the object to pull the object down

F = m a

The Restoring Force of spring to push the object up can be calculated by Hook's Law

Fs = - k y

The oscillation stops when the two forces are equal or the net force on object is zero

m a = - k y
y =  
a = -  


Any force acting on an object can be expressed in a differantial equation


Equilibrium is reached when F = Fs

s = ± j  
s =
