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?
