4. Speed, Velocity and Acceleration

5. TEKS 8.6A demonstrate and calculate how unbalanced forces change the speed or direction of an object’s motion TEKS 8.6B differentiate between speed, velocity and acceleration

6. Motion is a change in position relative to another object. Uniform motion - constant speed in a straight line Accelerated motion – motion that is changing in speed or direction

7. How fast an object is moving is called speed.

8. Speed is how far something travels (distance) in a given amount of time.

9. The formula for finding speed is Speed= distance time

10. The unit for speed is meters or kilometers (distance) and seconds or hours (time).

11. It looks like this: m/sec or km/hr

13. Sometimes, it is important to know the speed and direction an object is traveling.

14. Velocity is the term used when referring to the speed and a direction.

15. So, you might say the car is traveling at 50 km/hr, north.

16. Vectors can be used to show the direction of an object’s motion.

17. Which of these shows and which 25 m/sec 67 m/sec south 90 km/sec 13 km/sec speed velocity?

18. Acceleration

19. When a force is applied to a moving object, the object can speed up, slow down, come to a stop or change direction.

20. When a force changes the speed, direction or both of an object, we are changing the velocity of the object.

21. A change in velocity is called acceleration.

22. This is the change in velocity over a given period of time.

23. The formula for acceleration is acceleration = velocity time

24. Acceleration is measured meters per second per second or m/sec 2

25. An object falling to earth is subject to a change in acceleration of 9.8 m/s 2 due to gravity.

26. Examples of acceleration are…. stepping on the brakes

27. pedaling your bicycle faster

28. dropping your lunch tray to the floor…

29. a dog chasing its tail

30. a roller coaster climbing to the top of a hill.
