Physics
• Physics is a science that seek to explain and
understand matter and energy and their
interaction.
• Physics is a science and does utilize the
scientific method.
• Physics is the most basic and fundamental
science.
• Examples: electricity, motion, gravity,
magnetism, waves, sound, light
Scientific Method
•
•
•
•
1. Observation (qualitative and quantitative)
2. Questioning (why? How? When?)
3. Hypothesis (explanation, educated guess)
4. Prediction based upon hypothesis (if….,
then …..)
• 5. Experiment
• 6. Conclusion
Example
• 1. The car will not start.
• 2. Why won’t the car start?
• 3. The car will not start because the battery is
dead.
• 4. If I replace the dead battery, then the car will
start.
• 5. I replace the battery and then the car starts.
• 6. The hypothesis was correct.
Group Problem
• The grass is brown.
• Use the scientific method to explain why and
how the grass is brown.
Physics is the most basic science
• Recall in chemistry you became familiar with
atoms and parts of atoms such as protons,
neutrons, and electrons.
• In physics we currently have The Standard Model
on p. 3 of the Reference Table that says that
protons and neutrons are hadrons and, as such,
are made up of quarks held together by the
strong force. Electrons and neutrinos are leptons
and therefore lack quarks and strong force.
Proton
• Charge is +1
• Composed of 3 quarks held together by strong
force
• Up quark +2/3 and Up quark +2/3 and Down
quark – 1/3
Neutron
• Zero charge
• Made up of three quarks held together by the
strong force
• Up quark +2/3 and Down quark -1/3 and
Down quark -1/3
Anti-particles
• Same mass
• Opposite charge
• Particles and Anti-particles annihilate each
other with the release of energy
• E = mc^2
