Review: The Basics
Solve for “x” in each case.  You don’t need a calculator.  Seriously.  You don't.

3x2/ xy = 2zx2

q2 = op/x

54x = 9y

65/x  = 13

yx2 = c2  + 2ad

7000g + 19kg = x grams

(5m)(17m) = x

50 km/ 2 hr = x

What does “SI” stand for?
 
 

What are the SI units for length, mass and time?
 
 

How many millimeters are there in a meter?
 
 

How many meters are there in a centimeter?
 
 

Fill in the blank (use scientific notation as necessary):

100000 g = ________ kg = _________ ng = ___________ mg

Define “physics” in your own words.
 
 

Give a specific example from the everyday things around you of:

Mechanics -
 

thermodynamics -
 

wave phenomena -
 

optics -
 

electromagnetism -
 

Give an example of an occupation that uses physics and tell how physics relates to that occupation (Give specific concepts that are employed).
 
 
 
 

What are the rules for significant digits:
 
 
 
 
 

Significant digits: How many?
0.001 cm

$10

10.0 km

1.0001 m
 

Perform the following calculations using significant digits:

10 x 100.1 =

1.0001 x 10.0 =

0.001 x 10.0 =
 

Graphing:

Draw a linear graph
 

Draw an exponential graph
 

Define:

Dependant -

Independent -
