Bellwork:
    1.  If you are about to take a vacation and your parents want you to determine the average speed your    
         family will travel throughout your trip, how would you explain to them the method to do so? 

    2.  If you had to explain the concept of speed to someone right now, what would you say?

Goals: 
    -Be able to understand how speed and velocity are calculated.
    -Be able to explain the difference between speed and velocity. 
    -Be able to calculate the speed of an object using measure values.





Objectives:
                   -Be able to explain the difference between speed and velocity
                   -Be able to calculate the speed and/or velocity of an object

Discuss speed, displacement, and velocity.

Speed lab:  Students will determine their average speed for activities performed in class.

HW:   Finish lab questions.  Watch the video on how to graph the speed of an object.

Physics

Please pick up a prelab on the stool by the door. 

Bellwork:
    -Determine the speed of a plane that travels 3280km in a time of 16 hours. 

    -Explain how a graph can be used to analyze the motion of an object.  Justify your answer.

Discuss velocity vectors and graphing distance/displacement vs. time.

Explain the Lab:One-Dimensional Motion

HW: Finish Lab Questions, Read Chapter 3: Acceleration.  Make to take notes over the material.  We will wrap up the lab tomorrow and then begin discussing acceleration and gravity.
