1. Students will be able to contrast velocity and speed.
Goal 2
Students will solve for speed in the equation speed = distance/time using correct units. 
Students will be able to contrast velocity and speed.

2. Goal 1 Part 1

3. Goal 1 Part 2
Always has direction.

4. How do you know if you are moving?
Motion is relative.
Motion is defined as an object that is changing it's distance from another object.

5. What is a reference point?
A place or object used for comparison to determine if something is in motion.
An object is in motion if it changes position relative to a reference point.

6. Measuring Distance
SI unit for measurement:
Distance = Meters
Time = Seconds
Speed = Meters/Second

7. Goal 1 Part 1

8. Speed Calculation

9. Based on the video:
Distance was 100m, 
Time:
    Started sliding at 8s, landed at 14seconds
     = 6 seconds
What is his speed?

10. Using the Formula
Speed = Distance / time
Speed = 100m / 6 s =

11. Answer
16.6
Label your answer!

12. How to Label
Meters / Seconds = m/s
Also known as Meters per second

13. A harder question still
Calculate the Distance the boy travels if his speed is 2 meters per second and in 3 seconds.

14. A harder question still
Calculate the Distance the boy travels if his speed is 2 meters per second and in 3 seconds.
Formula is Speed times Time

15. Answer
2 meters/second times 3 seconds
2 x 3 = 6
What to label it?

16. Calculate the Distance the boy travels if his speed is 2 meters per second and in 3 seconds.

17. Average vs. Instantaneous
Average Speed.
Total distance divided by total time.
Instantaneous speed
Rate at which an object is moving at a given instant in time.

18. What is Velocity?
When you know both 
speed and direction of 
an object's motion you know the VELOCITY of the object.
Ex: 25 km/h Eastward
Important applications:  Air traffic controllers, Airplane pilots

19. Graphing motion
You can show the motion of an object on a line graph in which you plot distance versus time.
Y axis = distance (position)
X axis = time
At any point in time you can
note the distance and time
an object has traveled.
SLOPE = steepness of line
How fast one variable changes in realtionship to another.

20. Slope Slope = rise / run Same as distance / time
Different slopes show changes in speed.

22. Goal 1
Students will solve for speed in the equation speed = distance/time using correct units. 
Students will be able to contrast velocity and speed.
