Oscillatory Motion and Waves
The simplest type of oscillations and waves are related to systems that can be described by Hooke’s law: F = - kx , where F is the restoring force, x is the displacement from equilibrium or deformation, and k is the…
Practice this chapterThe simplest type of oscillations and waves are related to systems that can be described by Hooke’s law: F = - kx , where F is the restoring force, x is the displacement from equilibrium or deformation, and k is the… Periodic motion is a repetitious oscillation
An oscillation is a back and forth motion of an object between two points of deformation An oscillation may create a wave, which is a disturbance that propagates from where it was created
wave — a disturbance that moves from its source and carries energy. elastic potential energy — potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring. oscillation — a back and forth motion of an object between two points of deformation. restoring force — force acting in opposition to the force caused by a deformation.
Worked example
What does “wave” mean in Oscillatory Motion and Waves?
- 1Use the wording this chapter gives for wave.
- 2The book says: a disturbance that moves from its source and carries energy.
- 3Do not use the meaning of elastic potential energy. That term means potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring.
Result: a disturbance that moves from its source and carries energy
Why. That is the meaning this chapter gives for wave.
Do not swap wave and elastic potential energy. wave means a disturbance that moves from its source and carries energy. elastic potential energy means potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring.
