1. 3 things Kinetic Theory of Matter states.
    • 1.All matter is made of atoms and molecules (tiny particles)
    • .2.particles are always in motion
    • 3.all the same temperature, more massive particles move slower then less massive.
  2. Metric prefixes in order.
    nano, micro, milli, centi, kilo, mega, giga
  3. What is Distance?
    Distance is how far.
  4. What is Displacement
    Getting placed somewhere else.
  5. Accelereation
    get faster, slow down, change direction
  6. Constant Velocity
    Constantly getting faster or at constant speed = velocity
  7. What is the unit of force?
  8. Newton's Laws of Motions:
    • Law of Motion - An object at rest stays at
    • rest and an object in motion stays in motion
    • Law of Conservation of Energy - Energy can neither be created nor destroyed.
    • Law of Inersia - The ammount of force or energy put in is the ammount given back from the object you're pushing.
  9. What is Mass and what is Weight
    • Mass - how much the object is made up of
    • Weight - how much the object really weighs
  10. Kinetic Friction
    not moving
  11. Static Friction
  12. Two factors that affect an obj momentum?
    Mass and velocity!
  13. Mechanical Energy
    kinetic and potential
  14. kinetic energy
    any moving object
  15. gravitational potential energy
    energy with gravity to keep things in place
  16. elastic potential energy
    stretching or squeezing
  17. Conduction
    TRANSFER of energy as heat
  18. Convetction
    heat moves in a CURRENT
  19. Radiaton
    the heat moves in all directions in free space
  20. Solubility is what kind of change
  21. Physical
    never changes substance
  22. Chemical
    changes substance
  23. Phase Shifts
  24. Atom
    Tiny units that determine the properties of all matter
  25. Element
    cannot be broken down or seperated
  26. Compound
    substances made up of two or more different elements chemically combined
  27. molecule
    smalles uinit of a substance
  28. Pure substance
    single element or compound
  29. mixture
    combo of 2 or more substances
  30. homogenous
    uniform throughout
  31. heterogenous
    not uniform throughout
  32. atomic number
    how many protons are in an atom
  33. atomic mass
    number of protons plus neutrons
  34. Isotope
    same number of protons and electrons but different number of neutrons
  35. Cations
    postitive and lose electrons
  36. Which group NEVER forms ion
    group 18 b/c they have the octect rule already
  37. ionic bond
    electrons that transition from metal to non metal and are strong and energetic
  38. single covalent bond
    • 1 pair of electrons shard
    • weak and low energy
  39. Double co bond
    2 pair of electrons shared between non metals
  40. triple co bond
    • 3 pair elect shared between non metals
    • most energetic
  41. metallic bond
    • trans. between metal and metal
    • rare and weak
  42. hydrogen bond
    • between wtaer and water
    • loose attraction
    • water sticking
  43. 4 MAJOR types of chemical rxns
  44. 4 major types of chemical rxn
    • synthesis
    • decomposition
    • single disp
    • double disp
  45. rxn where water breaks down
  46. 4 main types of nuclear radiation in order of danger
    • Gamma
    • Alpha
