A satellite orbiting around the earth is a periodic motion even the motion of a balance ball set is a periodic motion. Periodic motion is when the motion of an object continually repeats itself, such as repeatedly moving back and forth or moving in a circular orbit. Periodic motion: Non-periodic motion: A motion repeating itself at regular intervals is regarded as periodic motion. PLAY. This oscillating motion continues until the pendulum eventually stops swinging. A motion that repeats itself is considered a non-periodic motion but not at regular periods of time. If you want to talk about the motion of the universe take Earth and the moon orbiting around the sun it is an object performing. The motion of the hands of a clock. What are two main forms of wave propagation? Any motion that repeats in a cyclic manner. Periodic Motion. Simple harmonic motion. When the cause of motion is a linear restoring force, the periodic motion is particularly simple and is called simple harmonic motion. The Law of Inertia states that an object moves in a straight line unless acted upon by a force, so periodic motion requires force to create this special type of motion. A periodic motion can be considered as any motion that repeats itself in a fixed time period. STUDY. The most basic type of periodic motion is that of a simple harmonic oscillator, which is defined as one which always experiences an acceleration proportional to its distance from the equilibrium position and directed toward the equilibrium position. 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. Give Two Examples of Periodic Motion. Periodic motion or harmonic motion is any motion that repeats at regular intervals. The period of the object's motion is defined as the time for the object to complete one full cycle. Unlike a spring, the restorative force is dependent on gravity and the angle (ɵ) of motion from the midpoint, rather than the mass suspended from the pendulum. Interval of time for a repetition, or cycle, of the motion is called a period, while the number of periods per unit time is called the frequency. longitudinal and transverse. Periodic motion . Being a time, the period is measured in units such as seconds, milliseconds, days or even years. The fact that the periodic motion is regular and repeating means that it can be mathematically described by a quantity known as the period. Motion repeated in equal intervals of time is called Periodic Motion. A planet revolving around the sun is a periodic motion. The hands of the watch and the electric fans are the examples of circular periodic motion. This type of motion is important to study since many natural systems are periodic. What is periodic motion? What is the name for periodic motion that is controlled by a retoring force and is not subject to damping? Simple harmonic motion is a sinusoidal function of time t. Periodic motion is observed in mass on a spring, simple pendulum, molecular vibration etc. Any motion that repeats (think of a position vs. time graph), no matter how complex, is called periodic. It is assumed that there is no friction or air resistance in this model. Periodic motion: A system is called periodic if it is invariant under a finite translation in time T. meaning: If $\vec{x}(t)$ is the trajectory of a particle then $\vec{x}(t+T)=\vec{x}(t)$ where T is the period of the system. If the motion of a moving particle is such that it passes through a definite point along the path of its motion in the same direction in a definite interval of time, this type of motion is called periodic motion. Physics Periodic Motion. Periodic motion is just another word for the motion because it describes any type of object performing movements even an object vibrating is another great example of periodic motion.
