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.
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.
