1. Introduction to motion graphs

2. Measuring Quantities Scalar __________________________ (number only) Examples Distance (20 meters) Speed (10 m/s) Mass (30kg) Vector __________________________ Examples Displacement (20 meters North) Velocity (10 m/s Eastbound) Force (20N downward)

3. Distance vs Displacement Distance “how much ground an object has covered“ _________________________ _________________________. Used to calculate ______________ Speed= change in distance change in time Unit: m/s Displacement it is the object's overall change in position; _________________________ _________________________. Used to calculate ______________ Velocity= change in displacement change in time Unit: m/s

4. _______________: I ran 5 miles on the treadmill _______________: I am still in my living room

5. What was the a) distance traveled? ______________________ b) displacement? _________________________

6. Distance- time graph Can be used to calculate _____________ Tells us how far we have moved each second that passes

7. Position- Time Graph Can be used to calculate ________________ Tells us how far away we are from a start point

8. BOTH Can be used to calculate ________________ Etc Position graphs just help out with “in which direction?”

9. How to calculate average speed or average velocity from a graph? Find the _________ of the line!! + slope= forward (positive direction) - slope = backward (negative direction) v= Δx / Δ t Velocity=

10. Your turn!! Calculate velocities.

12. Label: Constant speed Stationary Question: During which time range are you moving the fastest? 1.Identify. 2.Explain. 3.Then prove with calculations.
