Earth Science

The CMY color model, based on pigment, is widely utilized in film and print media, while the RGB color model, which pertains to light, is commonly used in CRT monitors. Color and brightness variations in light are influenced by the amplitude of light waves, with phenomena like the Doppler effect exemplifying such changes.

CMY which is the pigment color wheel

example for use would be film and prints

RGB witch in the light color wheel

Exapmle for use would be a CRT moniters

Physics

Force and motion

impulse and momentum
momentum

mass in motion

EX: your car moving

impulse

change in momentum

Ex: your car moving in one direction and a bug going towards your car hits your window

Gravity
Force that pulls you to the center of the earth

ex: when you kick a ball up in the air and when it comes back down that is because gravity is pulling it down.

Friction
resistence of an object

1`

Energy
total

Kinetic+ potential + thermal

thermal

energy realesed from friction

potential

possible energy at a certain point

Skatebord makes this when stopped

Kinetic

Energy in motion

Ex: skateboard in motion

Newtons Laws
Law 3

For every force there is an equal/oppstite reaction force

Law 2

Force = Mass X Acceleration

force=newtons

Law 1

law of inertia

Forces balanced /Object\ rest motion / \ stays stays

A body in stays in motion unless acted upon

Evidence: This is like when you slam on your brakes and your seat belt saves you from slamming into the front dash

Sound

Changes in pitch and volume
Volmume

amplitude

amount of energy in a wave

constructive interfernce

amplify each other

Pitch

how high or low a sound is

Hearing
4. brain
3. inner ear

cilia

cochlea

2. Middle ear

Three bones

1. outer ear

ear drum

auditory cannal

Pinna

Mechanical waves
any wave that traves through a medium

ex. when you throw a rock into the water and the water starts to ripple

light

Vision
Subtopic
Changes in color and brightness
The brightness changes by the amplitude of the wave
Doppler effect is an example for change in color

the light traveling past a person appears redder than if it was traveling towards you which would be bluer

Electromagnetic waves
A wave of light

Electricity and magnetism

magnetism
The movement of the electrons result in the atomic scale

One exapmpel for this is a regular magnet. you can used this to hang stuff on the fridge. People at junk yards use really strong magnets to pick up cars to put them into the crusher

Electricity
form of energy in charged particles
DC current edison

Only flows in one direction

Safer

Used for DC motors

AC current Tesla

electric current that reverses its direction many times a second

people didnt know alot about AC so they didnt know how to use it and control it

Usally used for power supplys

Exaple would be for a power house to supply energy to the city
