The document discusses key concepts related to motion including position, distance, speed, and acceleration. It defines position as the location of an object relative to a reference point and can be described using direction and distance. Distance refers to the total path traveled, while displacement is the straight-line distance between initial and final positions. Speed is the distance traveled per unit of time, while velocity includes both speed and direction. Acceleration refers to changes in an object's speed or direction over time.

2. WHAT TO EXPECT…

5. MANY THINGS AROUND US MOVE,
SOME MOVE SLOWLY AND
OTHERS MOVE QUICKLY

6. IN SCIENCE,
ENTAILS CAREFUL USE OF
TERMS AND QUANTITATIVE
OBSERVATION

7. WHERE?
QUESTION THAT
ANSWERS THE EXACT
POSITION OF THE OBJECT

8. WHERE?
POINT OF REFERENCE
SOMETHING THAT SEEMS STEADY
THAT IS USED TO
COMPARE THE POSITION OF AN
OBJECT.

9. HOW TO DESCRIBE THE POSITION OF AN
OBJECT?•DESCRIBING HOW FAR THE
OBJECT IS FROM THE POINT OF
REFERENCE
•DESCRIBING THE DIRECTION
RELATIVE TO THE POINT OF
REFERENCE

10. ACTIVITY 1:
WHERE IS IT?

11. INSTRUCTION:
A. IT IS RIGHT THERE.
B. TURN AND IT IS THERE.
C. WALK SLOWLY AND YOU WILL
GET THERE.
D. IT IS FROM HERE TO THERE

12. THE OBJECT IS
LOCATED UNDER THE
TABLE.

13. THE OBJECT IS
LOCATED ABOVE THE
REFRIGERATOR.

14. DESCRIBING THROUGH VISUALS

15. •WHAT IS THE POSITION OF THE
DOG?
•WHAT IS THE POSITION OF THE
TREE?

16. •WHAT IS THE POSITION OF THE
DOG WITH RESPECT TO THE
HOUSE?

17. •WHAT IS THE POSITION OF THE
TREE WITH RESPECT TO THE
DOG?

18. HOW FAR?
•QUESTION THAT
ANSWERS
LENGTH.

19. 1.GETTING THE TOTAL LENGTH OF
THE PATH TRAVELLED BY THE
OBJECT.
2.MEASURING THE DISTANCE
BETWEEN THE INITIAL AND
FINAL POSITION OF THE OBJECT.

21. DISTANCE VS. DISPLACEMENT
•DISTANCE IS THE MEASUREMENT
OF THE TOTAL LENGTH OF PATH
TRAVELLED BY AN OBJECT

22. DISTANCE VS. DISPLACEMENT
•DISPLACEMENT IS THE LENGTH
OF PATH FROM THE INITIAL AND
FINAL POSITION IN A STRAIGHT
LINE.

24. WHEN CAN
DISPLACEMENT BE EQUAL
TO ZERO?

25. CAN DISPLACEMENT BE
GREATER THAN
DISTANCE? WHY?

26. WHAT IF THE BALL, THE CAR,
AND THE DOG IN THE
ILLUSTRATION GO BACK TO
THEIR STARTING POSITIONS,
WHAT WILL BE THEIR TOTAL
DISTANCES? WHAT WILL BE
THEIR DISPLACEMENTS?

28. HOW FAST?
QUESTION THAT DESCRIBES
HOW SLOW OR FAST AN OBJECT
IS MOVING.

29. THIS QUESTION CAN BE
ANSWERED IN TWO WAYS:
SPEED &
VELOCITY

30. ARE YOU FAMILIAR WITH THE SIGNS BELOW?

31. SPEED•BY KNOWING THE SPEED, WE CAN
DETERMINE
WHO/WHICH MOVES FASTER.
THE TIME AT WHICH THE
OBJECT REACH THE
DESTINATION.

32. SPEED
•SPEED IS DEFINED AS
DISTANCE TRAVELLED
DIVIDED BY THE TIME OF
TRAVEL.

33. UNITS OF SPEED ARE…
•MILES/HOUR (MI/H)
•KILOMETERS/HOUR (KM/H)
•METERS/SECOND (M/S)

34. AVERAGE VS. INSTANTANEOUS SPEED
AVERAGE SPEED
REPRESENTS THE SPEED
THROUGHOUT THE TRAVEL.

35. AVERAGE VS. INSTANTANEOUS SPEED
INSTANTANEOUS SPEED IS
THE SPEED AT AN INSTANT.
SPEED AT A PARTICULAR
TIME.

36. AVERAGE VS. INSTANTANEOUS SPEED
INSTANTANEOUS SPEED CAN
BE EQUAL, GREATER THAN,
OR LESS THAN THE
AVERAGE SPEED.

37. SPEEDOMETER•A DEVICE USE TO MEASURE
THE INSTANTANEOUS SPEED
OF A VEHICLE.
•IMPORTANT TO DRIVERS SO
THEY WILL NOT EXCEED THE
SPEED LIMIT.

39. SPEED & DIRECTION
SPEED WITH
DIRECTION IS
KNOWN AS VELOCITY

42. THINK…
•AT CONSTANT DISTANCE, HOW IS
SPEED RELATED TO RELATED TIME
OF TRAVEL?
•AT CONSTANT TIME OF TRAVEL,
HOW IS SPEED RELATED TO THE
DISTANCE TRAVELLED?

43. WHO WAS TRAVELLING
FASTER THAN THE OTHER, A
PERSON WHO COVERED 10
METERS IN 5 SECONDS OR
THE ONE WHO TOOK 10
SECONDS TO COVER 20
METERS?

44. CHANGING SPEED AND
DIRECTION

45. ACCELERATION
•IS THE CHANGE IN SPEED
OR DIRECTION FOR A
PERIOD OF TIME.

46. ACCELERATION
THERE IS…
POSITIVE ACCELERATION -
ACCELERATION
NEGATIVE ACCELERATION -
DECELERATION

47. WHEN CAN WE CONSIDER AN OBJECT TO BE
ACCELERATING?
•WHEN THERE IS CHANGE
IN SPEED
•WHEN THERE IS CHANGE
IN DIRECTION

52. LET’S SUMMARIZE…
•IF AN OBJECT DOES NOT
CHANGE ITS POSITION AT A
GIVEN TIME INTERVAL, THEN IT
IS AT REST OR ITS SPEED IS
ZERO OR NOT ACCELERATING.

53. •IF AN OBJECT COVERS EQUAL
DISTANCE AT EQUAL INTERVALS
OF TIME, THEN IT IS MOVING AT
CONSTANT SPEED AND STILL
NOT ACCELERATING.
LET’S SUMMARIZE…

54. •IF AN OBJECT COVERS VARYING
DISTANCES AT EQUAL INTERVALS
OF TIME, THEN IT IS MOVING
WITH CHANGING SPEED OR
VELOCITY. IT MEANS THAT THE
OBJECT IS ACCELERATING.
LET’S SUMMARIZE…

55. IN SCIENCE,
MOTION IS DEFINED AS THE
CHANGE IN POSITION FOR A
PARTICULAR TIME INTERVAL.
