This document provides an overview of key concepts related to waves and oscillation. It defines equilibrium as a physical state where opposing forces are balanced. Simple harmonic motion is described as periodic motion about a point of equilibrium. Oscillation is defined as a repetitive variation between two or more different states about equilibrium. Examples of oscillators and simple harmonic oscillators are given. The document then discusses three types of waves - mechanical, electromagnetic, and matter waves - and defines transverse and longitudinal waves. Key concepts such as force, friction, inertia, elasticity, amplitude, frequency, displacement, and compression are also defined.

2. Equilibrium
A physical state where opposing forces exerted on a
mass are balanced. AKA resting point or zero state.

3. Simple Harmonic
Motion
Periodic motion about a point of equilibrium.

4. Oscillation
repetitive variation between two or more different
states about equalibrium.

5. Oscillator
Electronic circuit that produces a periodic
signal.

6. Simple Harmonic
Oscillator
Things like a pendulum or
tuning fork that produce a
generated frequency

7. Waves
Disturbance in a medium that propagates
with velocity which depends on the medium.

8. 3 Different Types of
Waves
Mechanical
Electro
Magnetic

9. Transverse Waves
Particle displacement is perpendicular
to wave
propagation.

10. Longitudinal
Waves
Particle displacement is parallel to wave
propagation.

11. Force
Push or pull action exerted on an object that
produces a change in movement or shape

12. Friction
Electromagnetic forces between charged particles
that resist the relative motion of interacting
surfaces,

13. Inertia
Property of a mass to remain at rest or in
uniform

14. Elasticity
The property of either
an object or medium to
return to its
original state after
being compressed,
stressed,
strained or distorted.

15. Amplitude!!!
Extent of particle
motion maximum
extent of
vibration, oscillation
or displacement from
equilibrium.

16. Frequency
Number of completed wave
cycles per unit of time

17. Displacement
Measurement of the magnitude and direction from
a point of equilibrium.

18. Compression
Area of increased pressure that forces
particles of a
medium closer together.

19. Conclusion
We are surrounded by waves. From the
music we listen to to the oceans we
swim in. Starting from a state of
Equilibrium and then being oscillated
into any number of different types of
waves. They can be enhanced in
magnitude via amplitude and even
compressed. They vary in frequency
and have the ability to move us
emotionally and physically.
