The Oscillatory Movement



When a body or object moves to and fro it is called oscillation but there is a condition that this movement must be around a main point or position. The oscillatory motion is also called as vibratory movement or motion. Generally, the oscillatory movement is termed as periodic movement of the object around a point or center. It means the body will come to touch the point of origin or center after short periods of times. In this movement the body moves forward and then backward but both types of movements are repetitive.

To understand the topic of Oscillatory Movement you must have a mass suspended from a spring. If you pull this mass down it will start to oscillate because of balance or center of origin. Different things are used to explain the Oscillatory Movement. Among the most popular and widely used materials and instruments the bob of a pendulum, steel ruler with bended ends from each side and a steel ball rolling in a curved container or vessel are famous. These are the widely used instruments and experimental objects that are frequently used by the physics teachers and instructors for the practical demonstration of Oscillatory Movement.

To produce the oscillatory motion in any body it is pulled away from the center or balanced position to release. When the object or mass is released it quickly moves towards the original point of equilibrium but doesn’t stop there because of force applied by the gravitational forces to help the object to come back towards the origin. However, the forces never end when the object reaches the center of origin but these forces pull it forward so the object gets peak once again. The force that attracts the pendulum or object towards the center is called gravitational force while the force that pulls the object forward is called the restoration force. It is observed that most of the moving objects produce sounds. These sounds are produced because of continuous vibrations in the oscillating objects. The theory is helpful to understand the basic structures and elements that posses Oscillatory Movement. All the rigid structures such as bridges vibrate when traffic passes over them. This movement might be up and down and to and fro so care is required while constructing such structures. The term or topic of Oscillatory Movement enables the students and experts to come across to learn about the motion in which bodies move to and fro.
