First scientist to demonstrate all objects fall at the same rate

Galileo
Natural selection (evolution)

Darwin
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
