Pre-Test  -  Speed and Velocity

*Please give a complete answer for each question in a complete sentence(s).
*Don't use root words to define words.
*Your answer must be definite; no "I don't know" allowed.
*Just give your best educated guess.  You will not be graded on your answers.

1)  Describe the meaning of motion.  Do not use any words that come from the root word "move" in your definition.
 
 
 
 

2)  Are speed and velocity the same?  Why or why not?
 
 
 

3)  Which metric units could we use to express speed? (HINT: You need to use a combination of units.)
 
 
 

4)  What is a scalar quantity?
 
 
 
 

5)  What is a vector quantity?
 
 

6)  Draw a diagram of a path from 24th and Mission Street to the front entrance of Horace Mann using vectors.
 
 
 
 
 
 
 
 
 
 
 

7)  Define path.
 
 
 
 
 

8)  Define displacement (NOT in relation to measuring volume).
 
 
 
 

9)  How are path and displacement similar?  How are they different?
 
 
 
 

10)  What is acceleration?
 
 
 
 

11)  Acceleration values must be written with units.  If you were told that the acceleration of a car was 10, how would you write this number with the correct units?
