The movement of an oscillating object can be to and fro, back and forth, or vibratory in nature. This motion is nothing but an oscillatory motion. Some employers have developed ergonomic programs to help workers adjust their pace of work and arrange office equipment to minimize problems. Series of oscillations are seen in cosmological model. Clinical research uses human volunteers to help researchers learn more about a disorder and perhaps find better ways to safely detect, treat, or prevent disease. A freely hanging Bob 6.

For example, the movement of planets around the sun, giant wheel, etc. Use splints or bands to decrease the strain on a tendon that occurs with sporting activities, such as tennis and golf. Avoid awkward body posture. For example, a pendulum, flapping of bird wings, etc. Physical therapy may relieve the soreness and pain in the muscles and joints. If persistent or acute pain is experienced in any area, do not ignore it. The blinking of eyes is a continuous motion of pupils and occurs at every interval of time. This is because the plates vibrate to and fro along with a central or mean position. Here, the kinetic energy generated by vibration gets converted to sound energy. Upon giving an oscillation to the pendulum, it will keep on oscillating till it comes to a rest position as the energy is nullified. 2.
