1. You can't get mad at weather because weather's not about you. Apply that lesson to most other aspects of life.Douglas Coupland

2. What is the displacement and the distance of the cross-country team if they begin at the school, run 10 miles and finish back at the school?

3. Distance = 10 miles Displacement = 0 miles

4. Use the diagram to determine the average speed and the average velocity of the skier during these three minutes.

5. Distance = 420 m speed = 140 m/min Displacement = 140 m velocity = 46.7 m/min

6. Determine the accelerations that result when a 12-N net force is applied to a 3- kg object and then to a 6-kg object.

7. F = m x a a = F/m For a 3 kg object a = 12/3 = 4 m/s 2 For a 6 kg object a = 12/6 = 2 m/s 2

8. WHAT IS THE DIFFERENCE BETWEEN SPEED AND VELOCITY?

9. VELOCITY IS SPEED PLUS DIRECTION.

10. WHAT IS THE DIFFERENCE BETWEEN MASS AND WEIGHT?

11. MASS IS A MEASURE OF HOW MUCH MATTER AN OBJECT CONTAINS. WEIGHT IS THE FORCE DUE TO GRAVITY ON AN OBJECT.

12. A net force of 15 N is exerted on an encyclopedia to cause it to accelerate at a rate of 5 m/s 2. Determine the mass of the encyclopedia.

13. F = m x a m = F/a So m = 15/5 = 3 kg

14. A B C 1)WHAT HAPPENS IN A? 6) WHAT IS THE 2)WHAT HAPPENS IN B? SPEED IN C? 3)WHAT HAPPENS IN C? 4)WHAT IS THE SPEED IN A? 5)WHAT IS THE SPEED IN B?

15. A B C 1)IN A, SPEED IS POSITIVE AND CONSTANT 2)IN B, THE OBJECT IS STOPPED 3)IN C, SPEED IS NEGATIVE AND CONSTANT 4)THE SPEED IN A IS 0.8 m/s 5)THE SPEED IN B IS 0 m/s 6)THE SPEED IN C IS -0.6 m/s

16. WHAT IS THE DIFFERENCE BETWEEN AN ELEMENT AND A COMPOUND?

17. AN ELEMENT CONTAINS ONLY ONE KIND OF ATOM. A COMPOUND IS COMPOSED OF PARTICLES (MOLECULES) MADE UP OF TWO OR MORE DIFFERENT KINDS OF ATOMS.

18. WHAT IS PHYSICAL SCIENCE?

19. THE STUDY OF CHEMISTRY AND PHYSICS.

20. WHAT IS THE DIFFERENCE BETWEEN A MIXTURE AND A PURE SUBSTANCE?

21. THE COMPOSITION OF A PURE SUBSTANCE IS FIXED, WHILE THE COMPOSITION OF A MIXTURE CAN BE VARIABLE.

22. CLASSIFY THE FOLLOWING AS HOMOGENEOUS MIXTURES OR HETEROGENEOUS MIXTURES: 1)AIR 2)OATMEAL COOKIES 3)PEPSI 4)18 KARAT GOLD RING 5)DIRT

23. CLASSIFY THE FOLLOWING AS HOMOGENEOUS MIXTURES OR HETEROGENEOUS MIXTURES: 1)AIR - HOMOGENEOUS 2)OATMEAL COOKIES - HETEROGENEOUS 3)PEPSI - HOMOGENEOUS 4)18 KARAT GOLD RING - HOMOGENEOUS 5)DIRT - HETEROGENEOUS

24. CLASSIFY THE FOLLOWING AS ELEMENTS OR COMPOUNDS: 1)HELIUM 2)WATER 3)METHANE GAS 4)LEAD 5)TABLE SALT

25. CLASSIFY THE FOLLOWING AS ELEMENTS OR COMPOUNDS: 1)HELIUM - ELEMENT 2)WATER - COMPOUND 3)METHANE GAS - COMPOUND 4)LEAD - ELEMENT 5)TABLE SALT - COMPOUND

26. WHAT IS HAPPENING IN THE GRAPH BELOW?

27. SPEED IS POSITIVE, AND IT IS INCREASING.

28. 1)WHAT IS HAPPENING IN A? 2)WHAT IS HAPPENING IN B? 3)WHAT IS HAPPENING IN C?

29. 1)ACCELERATION IS POSITIVE 2)ACCELERATION IS ZERO 3)ACCELERATION IS POSITIVE AND GREATER THAN A

30. WHAT HAPPENS IN EACH CASE?

31. 1)IN A, ACCELERATION IS NEGATIVE 2)IN B, ACCELERATION IS POSITIVE 3)IN C, THERE IS NO ACCELERATION 4)IN D, ACCELERATION IS POSITIVE, BUT LESS THAN IN B

32. A 50 kg OBJECT IS IN FREE FALL. WHAT IS THE ACCELERATION OF THE OBJECT.

33. IN FREE FALL, THERE IS NO AIR RESISTANCE, SO THE ACCELERATION IS 9.8 m/s 2

34. THE DENSITY OF MERCURY IS 13.5 g/ml. WHAT VOLUME WOULD YOU NEED TO HAVE 50 GRAMS?

35. Density = mass/volume Volume = mass/density = 50 / 13.5 Volume = 3.7 ml

36. Convert the following to scientific notation: 1)356700 2)0.00098 3)- 533,000 4)0.0721

37. Convert the following to scientific notation: 1)356700 = 3.567 x 10 5 2)0.00098 = 9.8 x 10 -4 3)- 533,000 = - 5.33 x 10 5 4)0.0721 = 7.21 x 10 -2

38. CONVERT THE FOLLOWING TO REGULAR NUMBERS: 1)3.82 X 10 -4 2)6.44 X 10 2 3)8.3 X 10 -7 4)5.88 X 10 5

39. CONVERT THE FOLLOWING TO REGULAR NUMBERS: 1)3.82 X 10 -4 = 0.000382 2)6.44 X 10 2 = 644 3)8.3 X 10 -7 = 0.00000083 4)5.88 X 10 5 = 588,000

40. CONVERT THE FOLLOWING TO METERS: 1)15 cm 2)1500 mm 3)1.6 km

41. CONVERT THE FOLLOWING TO METERS: 1)15 cm = 0.15 m 2)1500 mm = 1.5 m 3)1.6 km = 1600 m

42. WHAT IS THE FIRST THING YOU DO BEFORE YOU BEGIN A LAB?

43. READ THE INSTRUCTIONS.

44. WHAT IS THE DIFFERENCE BETWEEN A HYPOTHESIS AND A THEORY?

45. A HYPOTHESIS IS AN EDUCATED GUESS, WHILE A THEORY IS A PROVEN HYPOTHESIS.

46. WHAT IS MATTER?

47. ANYTHING THAT HAS MASS AND TAKES UP SPACE. YOU MATTER!!
