Mr. HernandezRoom 274
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
Supplies needed continued…

Tera (Trillion): 1012
Giga (Billion): 109
Mega (Million): 106
kilo (thousand): 103
hecto (hundred): 102
Deka (ten): 101
deci (tenth): 10-1
centi (hundredth): 10-2
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)
Newtons (N) Joules (J) Watts (W) Volt (V)
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!

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
