3.  The main topic of this chapter is __________, which is a change in an object’s position relative to a ___________ point.

4.  The main topic of this chapter is MOTION, which is a change in an object’s position relative to a ___________ point.

5.  The main topic of this chapter is MOTION, which is a change in an object’s position relative to a REFERENCE point.

6. 3 formulas we will be using

7. -- speed

8. 3 formulas we will be using -- speed -- momentum

9. 3 formulas we will be using -- speed -- momentum -- acceleration

10.  SPEED = distance divided by __________

11.  SPEED = distance divided by TIME

12.  50 m/s  200 mi/hr  20 cm/min

13.  Instantaneous speed is speed in an ___________ of time WHILE average speed is the _____________ of you r speed over a trip

14.  Instantaneous speed is speed in an INSTANT of time WHILE average speed is the _____________ of you r speed over a trip

15.  Instantaneous speed is speed in an INSTANT of time WHILE average speed is the AVERAGE of you r speed over a trip

16.  For example, you may have ______________ on your brakes when a dog runs in front of your car ….so slower speed at that moment……

17.  For example, you may have SLAMMED on your brakes when a dog runs in front of your car ….so slower speed at that moment……(THAT INSTANT of TIME)

18.  Another example would be if you ____________ when the stoplight turned green.

19.  Another example would be if you HIT THE GAS when the stoplight turned green.

20. Race Number Average Speed 1120 2130 3 4160  What is the average speed of all the races?

21. Race Number Average Speed 1120 2130 3 4160  What is the average speed of all the races? 120 +130+ 130+ 160 = 540 540 /4 = 135

23.  Dividing total distance by total time calculates average speed.  SO……..If the whole trip totaled 30 miles and took 3 minutes to go the 30 miles…..then (30 miles / 3 minutes) = 10 miles/minute

24. CLASS  Please turn to your partner and tell them quickly --MAIN TOPIC OF UNIT -- 3 types of formulas you will see --HOW TO FIND Speed / Instantaneous speed/Average speed NOW YOUR PARTNER EXPLAINS……

25.  Momentum is based on _______ and _________ of an object.

26.  Momentum is based on MASS and _________ of an object.

27.  Momentum is based on MASS and VELOCITY of an object.

28.  If the mass of an object is small, for the object to have a lot of momentum, it must be traveling relatively __________

29.  If the mass of an object is small, for the object to have a lot of momentum, it must be traveling relatively FAST

30.  If the object is traveling very slowly, for it to have a lot of momentum, its mass must be relatively __________

31.  If the object is traveling very slowly, for it to have a lot of momentum, its mass must be relatively LARGE

32.  Acceleration is when an object SPEED UP or _____________ or changes _______________  When you speed up = acceleration  When you slow down = acceleration  When you change direction = acceleration  A carousel is an example of acceleration

33.  Acceleration is when an object SPEED UP or SLOWS DOWN or changes _______________  When you speed up = acceleration  When you slow down = acceleration  When you change direction = acceleration  A carousel is an example of acceleration

34.  Acceleration is when an object SPEED UP or SLOWS DOWN or changes DIRECTION  When you speed up = acceleration  When you slow down = acceleration  When you change direction = acceleration  A carousel is an example of acceleration

35.  Acceleration is when an object SPEED UP or SLOWS DOWN or changes DIRECTION  When you speed up = acceleration (positive)

36.  Acceleration is when an object SPEED UP or SLOWS DOWN or changes DIRECTION  When you speed up = acceleration (positive)  When you slow down = acceleration (negative)

37.  Acceleration is when an object SPEED UP or SLOWS DOWN or changes DIRECTION  When you speed up = acceleration (positive)  When you slow down = acceleration (negative)  When you change direction = acceleration

38. CLASS  Please turn to your partner and tell them quickly --ABOUT MOMENTUM --Positive acceleration -- Negative Acceleration NOW YOUR PARTNER EXPLAINS……

39.  ________________ Acceleration is acceleration towards the _____________ of a curved or circular path

40.  CENTRIPETAL Acceleration is acceleration towards the _____________ of a curved or circular path

41.  CENTRIPETAL Acceleration is acceleration towards the CENTER of a curved or circular path

42.  Speed + direction = ______________________

43.  Speed + direction = VELOCITY

44.  Velocity is speed plus a direction.  50 mi/hr is speed of a car  5 0 mi/hr going North is the velocity of a car.

45.  If I give you 50 m/s and 50 m/s going North……the number is the same……….velocity just adds the _______________

46.  If I give you 50 m/s and 50 m/s going North……the number is the same……….velocity just adds the DIRECTION

47. CLASS  Please turn to your partner and tell them quickly --Centripetal Acceleration --What speed + direction is -- Why is the number the same in velocity and speed NOW YOUR PARTNER EXPLAINS……

48.  Horizontal Vertical

50.  Projectiles are _____________________ _____________________

51.  Projectiles are objects thrown/shot in air

52.  Displacement is the ______________ and ________________ of the object’s change in ____________

53.  Displacement is the DISTANCE and ________________ of the object’s change in ____________

54.  Displacement is the DISTANCE and DIRECTION of the object’s change in ____________

55.  Displacement is the DISTANCE and DIRECTION of the object’s change in POSITION

56. CLASS  Please turn to your partner and tell them quickly --Projectiles --Horizontal vs vertical -- Displacement NOW YOUR PARTNER EXPLAINS……
