It results in an oscillation which, if uninhibited by friction or any other dissipation of energy, continues indefinitely. Periodic motion of a body repeats the motion after a period of time example being the motion of a planet around the sun. All the oscillatory motions are not periodic such as the revolution of the earth is periodic but not an oscillatory motion. This video is unavailable. Periodic motion is defined as the motion which repeats itself after a regular interval of time. These include circular motion and back-and-forth motion. Examples of periodic motion are a tuning fork or motion of a pendulum if you analyze the motion you will find that the pendulum passes through the mean position only after a definite interval of time. If a body recurs its motion along a definite path, about a certain point after a fixed interval of time is called the periodic motion. When something repeats in a pattern ; Examples? AP Periodic Motion Examples: File Size: 1832 kb: File Type: pdf: Download File. Get Started. The requirement that the motion of a body or an object must satisfy to be periodic is that it possesses a definitive period where the least interval of time after which the periodic motion of a body repeats itself is called the period T. The motion of the hands of a clock. List five examples from daily life in which you see periodic motion caused by a spring or cord.? The angular frequency and … The fixed interval of time after which the motion is repeated is called the period of motion. Motion of simple pendulum is periodic.Motion of minute and second hand in a … Sorry!, This page is not available for now to bookmark. Motion of a planet around the sun. Pro Lite, Vedantu In periodic motion the moving path is fixed and at regular interval the body crosses a particular motion of the path from the same direction. Subscribe for more videos. Let’s take the example of a taxi service that provides the inter-city services to the public but there are plenty of taxis to drop the passengers. Pro Lite, CBSE Previous Year Question Paper for Class 10, CBSE Previous Year Question Paper for Class 12. It is due to the reason that the oscillatory motion is called harmonic motion. Translatory motion is the movement of a body both is … In the absence of friction, the motion tends to remain periodic. There are several situations where an external force can cause an object to be in periodic motion. 4. Ans: According to Newton’s first law i.e. The motion of a girl sitting in the swing. The running of the batsman between the wickets. For example, the phenomenon of flutter in aerodynamics occurs when an arbitrarily small displacement of an aircraft wing (from its equilibrium) results in an increase in the angle of attack of the wing on the air flow and a consequential increase in lift coefficient, leading to a still greater displacement. 84.6 minutes. Motion of the rocking chair in our home. The long elastic rubber is tied to the ankle of the person who then jumps off from the bridge or certain height.
