Radio Waves & Electromagnetic Fields SIM Homework
1) For this question, use the Radio Waves & Electromagnetic Fields simulation to
guide your understanding of how Radio broadcasting and Radio receivers work.
a) How is the radiating electric field (or elec
Exploring electric charges simulations
Warm-up: Fill in the table with the descriptions of each particle.
Can it move?
Activities: explore the fundamentals of charge and
Forces and the Laws of Motion chapter 4
Describe how force affects the motion of an object.
Interpret and construct free-body diagrams.
Force- an action exerted on an object which may change the objects state of rest or m
Sound and Wave Basics
Use the PhET sim Wave on a String for questions 1-6. http:/PhET.colorado.edu
Play around and get familiar with the sim first. Be sure to try out all the buttons.
1. Are you familiar with longitudinal and transverse waves?
Refraction PhET Lab
Use ray diagrams to model the refraction of light from air into glass.
Deduce whether the index of refraction for a material is a constant.
Verify Snells Law and use it to identify an unknown material.

Inquiry Lens Simulation
Introduction: Lenses are important for things like glasses, telescopes, microscopes, movie
projectors, and other devices. In this activity, we will be looking at how a convex lens affects the
TEMPERATURE AND INTERNAL ENERGY
Temperature: a measure of the average kinetic energy of the particles in a
Adding or removing energy usually changes temperature
The sensation of hot and cold can be misleading
The temperature is propo
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 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

DISPLACEMENT, VELOCITY, AND ACCELERATION
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.
Momentum: a vector quantity defined as the product of an objects mass and
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
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
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

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.
