Periodic Motion
In physics, periodic motion is motion in which the object moves in a regular or repetitive fashion (e.g. a pendulum). This type of motion has several special types: In physics, a wave is a disturbance that transfers energy without moving any material particles, or whose atoms oscillate, undulating back and forth, in a wavelike motion. In physics, a quantum mechanical system is a system that can be modeled as a collection of quantum particles, such as electrons, atoms, or photons. Quantum mechanical systems often exhibit quantum behavior. A quantum mechanical system can be in a superposition of many different quantum states, and can only be measured to be in one of those states.

In physics, oscillation, or oscillation, is the repetitive variation of some quantity about its mean value. The term may apply to a system (e.g., a mechanical system or an oscillating chemical reaction) or to a quantity that varies regularly (e.g., electric current, sound pressure, or displacement). Oscillation is often referred to as "vibrational" movement. In physics, frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. The SI unit of frequency is s?1, but usually a hertz (Hz) is used instead. In physics, kinetic energy is the energy that must be supplied to an object in order to accelerate it from rest to its stated velocity. In classical mechanics, the energy is a scalar, while in quantum mechanics it is a vector. In physics, potential energy is the energy that an object has due to its position relative to other objects. The object with the greatest potential energy will be at its lowest point, and the object with the least will be at its highest point. In physics, momentum is the product of mass and velocity. More generally, it is the product of one or more of the three universal physical quantities: mass, velocity, and force. When a body's position is not changed, its momentum remains constant, and the amount of momentum that body possesses is given by the same calculation as when it is moving: The mass of the body is multiplied by its velocity and then its velocity is multiplied by its mass. In physics, motion is the translation of an object from one place to another, or a change in place. In physics, it is described by the classical laws of motion. Motion in everyday life is an inherent property of matter. In physics, a velocity is a vector quantity that describes the speed and direction of movement of an object. The SI unit of velocity is m/s, but in most other systems the unit of velocity is m/s. The direction of a velocity is usually expressed with reference to some frame of reference, such as the direction of a particular axis or of a point in space. In physics, a force is a type of action that causes objects to accelerate. In the presence of a net force, the acceleration of an object is perpendicular to its velocity. For example, if a ball is moving upward, the net force on the ball is downward and it accelerates downward. In physics, the related concepts of force and momentum are defined as follows. A force is a push or a pull. A force has both magnitude and direction. The magnitude of a force depends on the amount of matter it acts on. The direction of a force is given by a vector which is described in terms of a displacement from a starting point. In physics, energy is a property of objects which can be transferred to other objects or converted into different forms. Energy can be transformed in various ways. For example, it can be transformed into mechanical energy, heat, light, or chemical energy, such as it occurs in chemical reactions. It is also the ability to do work on an object. In physics, a spring is a system that stores mechanical energy in the form of elastic potential energy. For the physics definition, see Spring (physics) In physics, a force field is the result of a field acting on a particle. The field is an analogue of a static electric field in classical electromagnetism. In quantum theory, a force field is the result of a field acting on a quantum mechanical system.
