Motion 1: Velocity and Acceleration
Answer the following in order on notebook paper.

Show how you set up the solution to assigned problems.

Define:

frame of reference

displacement

the symbol “D”

average velocity

instantaneous velocity
 

What is meant by the term “one dimensional”?
 
 

What is meant b the term “at rest”?
 
 

What is meant by positive and negative displacement?
 
 

If you travel from Fort Worth to Houston (290 miles) in 5 hours, what is your average velocity?  Does that mean that you travel that velocity the entire time? Explain.
 
 

Distinguish between speed and velocity.
 
 

Consider a position – time graph:

a. What are the units on the axes?
 

b. How do you calculate slope of a line?
 

c. What would the units of the slope be?
 

d. What does the slope represent?
 

e. What is indicated by a positive versus a negative slope?
 

f. What is indicated by a straight versus a curved line?
 
 

What is meant by the term “tangent line”?
 
 

Consider the curved line in figure 2-7.  What happens to the slope of the tangent line as time increases? What does this tell us about the velocity?
