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
