- Repeat the above step till the end of line is reached. Make a knot at the end of the line.
- Now, straighten the thread and measure the length of the two knots on a scale.

Every body at rest is in its equilibrium position. At this position, no external force is acting on it. Therefore, the net force acting on the body is zero. Now, if this body is displaced a little from its equilibrium position, a force acts on the body which tries to bring back the body to its equilibrium position. This force is the restoring force and it gives rise to oscillations or vibrations.
