Proposed the earth travels around the sun
Copernicus
Discovered the universe is expanding
Hubble
Developed three laws of motion
Newton
idea that the laws of physics are the same throughout the universe
Universality
Logical and orderly methods of solving problems
Scientific Method
Measure of how much "stuff" an object contains
mass
Push or a Pull
Force
LIst the steps to the Scientific Method
1. Problem
2. Information
3. Hypothesis
4. Experiment
5. Data
6. Conclusion
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
Name Five science process skills
1. Classifying (grouping)
2. Communicating (graphs, drawings)
3. Controlling variable (fairtest)
4. Hypothesizing
5. Questioning
Energy
the ability to do work
Work
a force moves an object a certain distance
What is the formula for work
W=FD
Work=ForceXDistance
Energy is neither created nor destroyed
Law of Conservation of Energy
First law of Thermodynamics
Potential energy
energy of position
Kinetic energy
energy in motion
As energy is transferred from one object to another, some energy is "lost" in the form of heat
Second Law of Thermodynamics
Speed=
distance/time
Mass
matter in an object (kilograms)
Weight
force of gravity (newtons)
Galileo 3 ways to describe motion
Speed
Velocity
Acceleration
Inertia
Lazy
1st Law of Motion
An object at rest remains at rest
2nd Law of Motion
Force= massX acceleration
f=ma
3rd law of Motion
For every action there is an equal and opposite reaction
