AP Physics 1

Advanced Placement Physics 1 covers the fundamentals of mechanics, waves, and electricity in preparation for college-level physics.

Basic Concepts

Waves and Sound

Vibrations and Energy Transfer

Waves are disturbances that transfer energy from one place to another without moving matter permanently. Sound is a type of mechanical wave that travels through air, water, and solids.

Types of Waves

  • Transverse Waves: The disturbance is perpendicular to the direction of travel (like light waves).
  • Longitudinal Waves: The disturbance is parallel to the direction of travel (like sound waves).

Properties

  • Wavelength (\(\lambda\)): Distance between two consecutive wave peaks.
  • Frequency (\(f\)): Number of waves passing a point per second.
  • Amplitude: Height of the wave; relates to energy.

Sound in the Real World

From music and speech to sonar and echolocation, sound waves play a vital role in communication and technology.

Examples

  • You hear music because sound waves travel from the speakers to your ears.

  • Ocean waves carry energy to the shore, causing movement of sand and shells.

In a Nutshell

Waves transfer energy, and sound is a wave that lets us hear the world.
