1. November 12 th,2015 Materials: AGENDA  Notebook  Pencil  Folder  Packet Agenda:  Agenda  Bell work  Brain pop  Vocab  Chapter 1.1 Objective: Today we will describe an objects position and motion. No Gum Please! Daily Question: Pick an object in the room and write down directions to find it (do not describe object)

2. Motion Notes Position- Of a place or an object is the location of that place or object. (practice with shoulder buddy) Motion-A change in position, over time, relative to a reference point. Reference Point- A location in which you compare other locations to.

3. Motion Key points-reading sum You can measure from two points with standard unit of measurement- Kilometers (km), Meters (M), or Centimeters (cm). A change in position is evidence motion happened. A change in position tells you motion took place but not how quickly (speed) the object changed position.

4. Reference Point Scenarios Suppose you are in a train, and you cannot tell if you are stopped or moving. Outside the window, another train is slowly moving forward. What could be happening? Your train is stopped, and the other train is moving slowly forward… The other train is stopped, and your train is moving slowly backwards… Both trains are moving forward, with the other train moving a little faster… Your train is moving very slowly backward, and the other train is moving slowly forward… Could you be sure as to which is actually happening??

5. Reference Point Examples

7. Speed Position can change at different rates Distance an object moves in an amount of time Formulas Distance / Time S=D÷TD=T·ST=D÷S 30mph; 15 cm/year; 500 m/s

8. Suppose there’s a TORNADO that’s 1 mile wide, and it’s going 40 mph… What else is important?!?!? It’s Direction! Velocity is a Speed in a Direction! 15 Mph Northwest; 200 m/s South; 40 cm/ms Left Velocity

9. Acceleration Change in Velocity over time Remember: Velocity is Speed AND Direction “Speeding Up” = Acceleration (Positive #) “Slowing Down” = Deceleration (Negative #) Turning (Change in Direction) = Acceleration

10. Calculating Acceleration THIS IS TOUGH!!! Final Velocity – Initial Velocity Time V final – V initial T

11. Acceleration Problem! Julio starts sliding with a velocity of 1m/s south. After 3 seconds, his velocity is 7m/s south. What is Julio’s acceleration? Final Velocity – Initial Velocity Time 7 m/s – 1 m/s 3s 6 m/s 3s 2 m/s s 2 m/s 2

12. Practice! At the top of your notebook paper, please write the following formulas: Speed/Distance/Time Formulas: S=D÷TD=T·ST=D÷S Acceleration Formula: Final Velocity – Initial Velocity Time
