**AN UNBELIEVABLE EXPERIENCE!!**

Physics: AN UNBELIEVABLE EXPERIENCE!!

2
**What is Physics? The science of matter and energy and the**

interaction of the two.

3
**Class 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.

4
**Labs Want to create an awesome color tee shirt?**

You will learn how different colors mix together to form new colors and patterns.

5
**Waves and Energy Transfer**

Concepts Motion Momentum Force Thermodynamics Uniform Acceleration & Kinematic Equations Waves and Energy Transfer Vector Sound Waves Work and Energy Light Waves

6
**Motion V=d/t Kinematics- the study of motion of an object**

Motion involves: Displacement (d)- measure of change of position Time (t)- time it takes to change position Velocity (v)- change in position per interval of time V=d/t

7
**Force A force is a push or pull on an object**

Force is measured in Newtons which is a kilogram times a meter per second squared. Force = mass x acceleration Force of gravity keeping the riders in their seats.

8
**Uniform 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+at d=Vi(t)+a(t)^2 Vf^2=Vi^2+2a(d) Uniform acceleration is measured in meters per second squared. d= displacement a= acceleration t= time Vi= initial velocity Vf= final velocity

9
**Vector Vector- anything that has magnitude and direction**

Vector Resolution- the process for determining the magnitudes of components of a vector in 2 dimensions Formulas: 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)^1/2 V= vector Rx= resultant of x-axis Ry= resultant of y-axis

10
**Work and Energy Potential Energy- energy of position or configuration**

Conservation of Energy- energy cannot be created or destroyed U= m(g)(h) u- potential energy m- mass g- acceleration due to gravity h- height above zero point Ki- intial kinetic energy Ui- intial potential energy Kf-final kinetic energy Uf-final potential energy Ki + Ui = Kf + Uf

11
Momentum Momentum 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- momentum m- mass v- velocity

12
Thermodynamics Thermodynamics is the study of heat, thermal energy, and involves: States of matter Temperature Heat Thermal equilibrium Change of state Thermal energy transfer Laws of Thermodynamics Thermal energy- the internal motion of the molecules that make up an object

13
**Waves and Energy Transfer**

Wave motion transports energy from one point to another. Wave pulse: Traveling wave: 3 Types of Waves: Mechanical Electromagnetic Matter

14
Waves Reflection of waves: Refraction of waves: Diffraction of waves:

15
**Sound 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

**Closed-Pipe Resonator**

Open-Pipe Resonator Clarinet Flute

17
**Light Waves The study of light is called ray optics.**

Colors of the Spectrum The 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 second R E D O A N G Y L W B U I V T
