1. Notes
Test01

2. To calculate acceleration
Start Velocity – Final Velocity
Time

3. What’s your velocity
You leave NYC and travel south to mobile in one hour you travel 90 km
Must include units and direction (south, north, east or west)

4. Answer
90 km/h south

5. You drop an object at towards earth at 9
You drop an object at towards earth at 9.8 m/s will its velocity increase, decrease, or stay the same?

6. Answer
Increase by 9.8 m/s

7. A ball drop of a rooftop. What’s the ball velocity after 4 sec?

8. 39.2 m/s
9.8 (space) X 4

9. Galileo
The RATE is NOT affected the MASS
At which an object falls

10. SI Unit for Speed = M/S

11. Components of projectile motion have no affect on each other

12. Projectile motion Accelerated downward/gravity Accelerate horizontally
Thrown/ horizontal push

13. Projectile motion :
Horizontal or vertical

14. Projectile motion :
Horizontal or vertical

15. On the moon
Feather and a rock would have the same mass/weight on the moon

16. Earth mass triple
Your weight and gravity will INCREASE

17. Acceleration
Ride your bike north 100 m CONSTANT speed for 5 min what’s your acceleration?

18. NO acceleration CONSTANT did not accelerate

19. Example of acceleration is a car turning a corner

20. Velocity
Running 50 m/s forward chasing someone at 4 m/s

21. Answer 54 m/s foward
= 54 m/s forward

22. Bull’s eye
Always aim above the bulls eye

23. Acceleration to occur
Change in speed , direction & Velocity

24. Velocity of 32 m/s in 3 sec he stop
What’s the acceleration

25. Answer
= 10.7
time

26. The curve path traveled by a thrown baseball …projectile motion
Example …leaping frog

27. A reference point for determining position and motion could be
Earth’s surface
A moving object
A building

28. When gravitational force changes weight changes

29. You move from the front of the bus to the back of the 25 m/s east at a rate of 1 m/s What’s your velocity

30. 25-1 = 24 m/s east

31. How fast are you able to run
200m race in
25 seconds

32. 8 m/s
200 = 8 m/s 25

33. Parachutes
Increase air resistance

34. Orbital motion
Motion and Free Fall

35. 3 balls drop @ same time &height
They would all hit at the same time

36. A student riding a bike and covers one block every 10 seconds shows:
Show constant speed and Velocity

37. Skating is an example
Negative acceleration
acceleration
deceleration

38. Average speed
A bird flys 100m for 10 s, 300 m for 10 s than 200 m for 5 sec

39. Answer
100/ / /5 =26.7 m/s

40. Anwser
Somton 5 m/s/s
