2What is Physics? The science of matter and energy and the interaction of the two.
3Class Requirements Sleep at least 8 hours a night. Be sure to eat your Wheaties!(every morning)Know how to say and spell Matysczak.Mrs. Matysczak says homework is an option…but in reality it is a necessity.
4Labs Want to create an awesome color tee shirt? You will learn how different colors mix together to form new colors and patterns.

6Motion V=d/t Kinematics- the study of motion of an object Motion involves:Displacement (d)- measure of change of positionTime (t)- time it takes to change positionVelocity (v)- change in position per interval of timeV=d/t
7Force A force is a push or pull on an object Force is measured in Newtons which is akilogram times a meter per secondsquared.Force = mass x accelerationForce of gravity keeping the riders in their seats.
8Uniform Acceleration & Kinematic Equations Uniform Acceleration occurs when the speed of an object changes at a constant rate.Formulas:d=1/2t(Vf+Vi)Vf=Vi+atd=Vi(t)+a(t)^2Vf^2=Vi^2+2a(d)Uniform acceleration is measured in meters per second squared.d= displacementa= accelerationt= timeVi= initial velocityVf= final velocity
9Vector Vector- anything that has magnitude and direction Vector Resolution- the process for determining the magnitudes of components of a vector in 2 dimensionsFormulas:V x-axis= vector x (cosine of the angle)V y-axis= vector x (sine of the angle)Resultant= (R x^2 + R y^2)^1/2V= vectorRx= resultant ofx-axisRy= resultant ofy-axis
10Work and Energy Potential Energy- energy of position or configuration Conservation of Energy- energy cannot be created or destroyedU= m(g)(h)u- potential energym- massg- acceleration due to gravityh- height above zero pointKi- intial kinetic energyUi- intial potential energyKf-final kinetic energyUf-final potential energyKi + Ui = Kf + Uf
11MomentumMomentum is the measure of how hard it is to stop an object, which deals with Newton’s 2nd Law.Formula:P= m(v)The unit for momentum is a kilogram times a meter per second.P- momentumm- massv- velocity
12ThermodynamicsThermodynamics is the study of heat, thermal energy, andinvolves:States of matterTemperatureHeatThermal equilibriumChange of stateThermal energy transferLaws of ThermodynamicsThermal energy- the internal motion of the molecules that make up an object
13Waves and Energy Transfer Wave motion transports energy from one point to another.Wave pulse:Traveling wave:3 Types of Waves:MechanicalElectromagneticMatter

15Sound Waves Sound waves are the compression of waves. The frequencies of a sound wave is the number of oscillations per second.Amplitude is the loudness of the sound.The speed of sound in air formula:(T)T- temperature
17Light Waves The study of light is called ray optics. Colors of the SpectrumThe study of light is called ray optics.Light waves travel in a straight line path, therefore represented by a ray.The speed of light waves in a vacuum (c) is constant.c= 3 x 10^8 meters/per secondREDOANGYLWBUIVT
