Physics Course/Oscillation/Oscillation Up and Down

The Oscillation up and down of a Spring 100px]] 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 1 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 Fs = - Fa m a = - k y y = a = - 2 Any force acting on an object can be expressed in a differential equation Equilibrium is reached when Fs = - Fa s = ± j s = ± j s =
