The Oscillation up and down of a Spring[edit | edit source]
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[edit | edit source]
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[edit | edit source]
Any force acting on an object can be expressed in a differential equation
Equilibrium is reached when
- Fs = - Fa
- s = ± j
- s = ± j
- s =
