Welcome to Physics

Needed everyday Binder 1” or 2”

1” good for one semester2” good for whole year

Pencil and a PenPencil # 2Pen must be Blue or Black ink!

Supplies needed

GPS Planner Use it!

Composition Book Lab write ups

Calculator Oh yeah you need that!

Physics bookNot in here

Tera (Trillion): 1012

milli (thousandth): 10-3

micro (millionth): 10-6

nano (billionth): 10-9

pico (trillionth): 10-12

base: 100

To convert from, say, kilometers to centimeters, write your quantity:

10 km Don’t forget to include your decimal

point!!! Count the number of spaces from “k” to “c” Move the decimal that many spaces in that

direction.

A couple of things to keep in mind: The letters in black differ by one decimal

place The letters in red differ by three decimal

places

Meters (m) Seconds (sec) Grams (g) Liters (L) Hertz (Hz)

Some base units used in Physics:

Scientific Notation To convert from regular to scientific:

24,560,000,000 kg Move the decimal point so that the number is

between 1 and 9 (count the number of places that it moved)

Round the decimal part to the second place Slap a “x 10” at the end of the number Give the 10 an exponent- the number of spaces

you counted If you moved the decimal to left: (+) exp. If you moved it to the right: (-) exp.

Solving Equations Let’s say we have this

goofy-lookin’ equation:

New Line!

And you must solve for “v”1. Circle Mr. Stinky2. Identify the furthest thing

from Mr. Stinky & how it’s connected (+, -, x, or ÷) – Reverse order of operations

3. Make it move to the other side of the equal sign by doing the opposite function

4. Just make sure you do it to BOTH sides of the equal sign!!!!

5. Write a new line & repeat the process!

Solving Equations Let’s say we have this

goofy-lookin’ equation:

New Line!!!

And you must solve for “a”1. Circle Mr. Stinky2. Identify the furthest thing

from Mr. Stinky & how it’s connected (+, -, x, or ÷) – Reverse order of operations

3. Make it move to the other side of the equal sign by doing the opposite function
