TEMPERATURE AND INTERNAL ENERGY
TEMPERATURE
Temperature: a measure of the average kinetic energy of the particles in a
substance
Adding or removing energy usually changes temperature
The sensation of hot and cold can be misleading
The temperature is propo
SOUND WAVES
SOUND WAVES ARE PRESSURE WAVES
PRODUCTION OF SOUND WAVES
All sound waves are longitudinal and are produced by vibrating objects.
Sound waves must have a medium to travel through.
Unlike waves along a spring, sound waves in air spread out in al
SCIENTIFIC NOTATION
Scientific notation is a way to write numbers using exponents. Usually it is a
simplified way of writing very large or very small numbers . A positive exponent
indicates a number larger than one and a negative exponent indicates a numb

FRAME OF REFERENCE
Frame of Reference: a coordinate system for specifying the precise location of
objects in space.
Motion takes place over time and depends upon the frame of reference.
LINEAR MOMENTUM
Momentum: a vector quantity defined as the product of an objects mass and
velocity
Momentum describes an objects motion
p = mv
The direction of the momentum is the direction of the velocity.
The SI units are kilogram-meters per second (kg-
AREAS WITHIN PHYSICS
Physics is the study of the physical world.
Topics include: mechanics, thermodynamics, waves, optics,
electromagnetism, relativity, quantum mechanics
Just like any other sciences physics uses the scientific method to
understand a
MAGNETISM
MAGNETS
The ends of magnets are called poles. There is a north pole and a south pole. The
names derive from the behavior of a magnet on Earth (North points north and
South points south).
Like poles repel; unlike attract.
Magnetic poles alway
Graphing
ANALYZING DATA
Tables, graphs, and equations can make data easier to understand.
Graphs allow you to see a pattern or trend and the shape of the
graph also provides information about the relationship between the
variables.

ELECTROMAGNETIC INDUCTION
INDUCED CURRENT
Just as magnetic field can be formed by a current in a circuit, a
current can be formed by moving a portion of a closed electric circuit
through an external magnetic field.
The process of inducing a current in
