SEMESTER PROJECT By: Andrew Braunm

Momentum

Something that describes movement. Formula- p= F*v Measured- kg-m/s Examples- two people running one

person tall and one person small

Work

When you use a force to a distance Formula- work= force * distance Measured in jewels Examples- moving a stool

Electromagnetic waves

Does not need a medium Examples- lightning, lights

Electromagnetic spectrum

Is the range of all possible frequencies electromagnetic.

The scale ranges by colors. There are radio , microwaves , inferred,

uttalight , uv rays , x rays, gamma rays The slowest is radio waves which are 10.4 The fastest is 10.24

Reflection

Its when light reflects off of an object Sun light on a mirror Any glass object will reflect off of

something

Absorption

When it gets absorbed Black paint The color black is the only on that

absorbs sun light.

Transition

Can see the shape but cant see the object

Stained glass Plastic Fog Ice

Transparent

Can see through it Glass Ice Windows plexie glass

Opaque

Cant see through it. Wood Metal Ice All and any solid shape or form

How is lightning formed

Build of the charge Separation Positive goes to the top Negative goes to the bottom Then releases a lightning bolt

Resistance

When something creates friction it slows it down

A drill with Barings in it Car breaks

Ground

Something that goes on the top of a tall building to prevent a fire.

It sends the lightning bolt into the ground

Static electricity

When you rub two objects together Rubbing a balloon in someone's hair

Switch

Its an object that turns on and off the power

Voltage

It is the power being sent to the switch

Conductors

The copper wire This was not hard to learn. It was a good

lesson

Power source

The object that’s benign powered

Series

One path If you cut the wires then wont work.. It wont power the object.

Parallel

Multiple paths. If you cut the wire it will still work. It just wont power that object.

Power

Scientific method

Research question- what your doing your lab on.

Variables- independent, dependent, and constant.

Hypothesis- if and then statement. Procedure- steps to follow during

experiment Graph- data Conclusion- what happen during the

experiment. This was a little hard to learn

Acceleration

Its telling you how much speed you gained.

Formula- a = vi-vf/t Examples- a racecar

Speed

Tells you how fast your going. A car going 50 mph

Sound waves

They need a medium. Examples- a computer, speakers,

everything that has a medium.

Electromagnetic waves

They don’t need medium. Light.

Atoms

Atoms build up a object.
