    Darwin
  3. Proposed the earth travels around the sun
    Copernicus
  4. Discovered the universe is expanding
    Hubble
  5. Developed three laws of motion
    Newton
  6. idea that the laws of physics are the same throughout the universe
    Universality
  7. Logical and orderly methods of solving problems
    Scientific Method
  8. Measure of how much "stuff" an object contains
    mass
  9. Push or a Pull
    Force
  10. LIst the steps to the Scientific Method
    • 1. Problem
    • 2. Information
    • 3. Hypothesis
    • 4. Experiment
    • 5. Data
    • 6. Conclusion
  11. Name 3 characteristics that separate science from non science
    • - If it is real it can be measured
    • - Nature and light change rapidly and often year to year
    • - Knowledge about the universe and methods used to gain knowledge
  12. Name Five science process skills
    • 1. Classifying (grouping)
    • 2. Communicating (graphs, drawings)
    • 3. Controlling variable (fairtest)
    • 4. Hypothesizing
    • 5. Questioning
  13. Energy
    the ability to do work
  14. Work
    a force moves an object a certain distance
  15. What is the formula for work
    W=FD

    Work=ForceXDistance
  16. Energy is neither created nor destroyed
    Law of Conservation of Energy

    First law of Thermodynamics
  17. Potential energy
    energy of position
  18. Kinetic energy
    energy in motion
  19. As energy is transferred from one object to another, some energy is "lost" in the form of heat
    Second Law of Thermodynamics
  20. Speed=
    distance/time
  21. Mass
    matter in an object (kilograms)
  22. Weight
    force of gravity (newtons)
  23. Galileo 3 ways to describe motion
    • Speed
    • Velocity
    • Acceleration
  24. Inertia
    Lazy
  25. 1st Law of Motion
    An object at rest remains at rest
  26. 2nd Law of Motion
    Force= massX acceleration

    f=ma
  27. 3rd law of Motion
    For every action there is an equal and opposite reaction
