Vibrations

Vibrations. A vibration is a repeated back and forth motion. Examples are a child on a swing, a pendulum, a spring with an attached weight, a drum being struck, a guitar string being strummed, and alternating current. Waves. A wave is a vibration traveling through time.

Vibrations and Waves

Vibrations and Waves. Vibration: a repeating back-and-forth motion A vibration cannot exist in an instant Wave: a disturbance that repeats regularly in space and time A wave is a vibration in space and time Waves move energy from one position to another, not matter. Ex: Light and sound.

Vibrations and Waves. the basis of sound and light. Pendulum. Back and forth motion of pendulum called simple harmonic motion (SHM) Period is time it takes to swing back and forth. Displacement is how far the pendulum moves from the centerline Period is dependent on string length

Vibrations and Waves

Vibrations and Waves. They are All Around!!!. Periodic Motion is anything which repeats on a regular cycle. This can include large scale motion such as rotation and orbit of the Earth. It can also include the fluctuations of an electromagnetic wave!!. This can include Mass on a Spring!!.

VIBRATIONS AND WAVES

VIBRATIONS AND WAVES. Hooke's Law One of the properties of elasticity is that it takes about twice as much force to stretch a spring twice as far. That linear dependence of displacement upon stretching force is called Hooke's law. The idea behind Hooke's Law:

Vibrations and Waves

Vibrations and Waves. Vibration and Motion. Periodic Motion. Periodic Motion Notice a clock pendulum swinging back and forth. You would notice that every swing followed the same path, and each trip back and forth took the same amount of time. This action is an example of vibrational motion.
